Check if an operation can be paginated.
Creates a listener for the specified Application Load Balancer or Network Load Balancer.
To update a listener, use ModifyListener . When you are finished with a listener, you can delete it using DeleteListener . If you are finished with both the listener and the load balancer, you can delete them both using DeleteLoadBalancer .
This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple listeners with the same settings, each call succeeds.

Creates an Application Load Balancer or a Network Load Balancer.
When you create a load balancer, you can specify security groups, public subnets, IP address type, and tags. Otherwise, you could do so later using SetSecurityGroups , SetSubnets , SetIpAddressType , and AddTags .
To create listeners for your load balancer, use CreateListener . To describe your current load balancers, see DescribeLoadBalancers . When you are finished with a load balancer, you can delete it using DeleteLoadBalancer .
For limit information, see Limits for Your Application Load Balancer in the Application Load Balancers Guide and Limits for Your Network Load Balancer in the Network Load Balancers Guide .
This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple load balancers with the same settings, each call succeeds.
For more information, see Application Load Balancers in the Application Load Balancers Guide and Network Load Balancers in the Network Load Balancers Guide .

[REQUIRED]
The Amazon Resource Name (ARN) of the listener.
[REQUIRED]
The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .
Information about a condition for a rule.
The field in the HTTP request. The following are the possible values:
The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.
If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.
If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.
Information for a host header condition. Specify only when Field is host-header .
One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
Information for a path pattern condition. Specify only when Field is path-pattern .
One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .
Information for an HTTP header condition. Specify only when Field is http-header .
The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.
One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
Information for a query string condition. Specify only when Field is query-string .
One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.
If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
Information about a key/value pair.
The key. You can omit the key.
The value.
Information for an HTTP method condition. Specify only when Field is http-request-method .
The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
Information for a source IP condition. Specify only when Field is source-ip .
One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.
If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .
[REQUIRED]
The rule priority. A listener can't have multiple rules with the same priority.
[REQUIRED]
The actions. Each rule must include exactly one of the following types of actions: forward , fixed-response , or redirect , and it must be the last action to be performed.
If the action type is forward , you specify one or more target groups. The protocol of the target group must be HTTP or HTTPS for an Application Load Balancer. The protocol of the target group must be TCP, TLS, UDP, or TCP_UDP for a Network Load Balancer.
[HTTPS listeners] If the action type is authenticate-oidc , you authenticate users through an identity provider that is OpenID Connect (OIDC) compliant.
[HTTPS listeners] If the action type is authenticate-cognito , you authenticate users through the user pools supported by Amazon Cognito.
[Application Load Balancer] If the action type is redirect , you redirect specified client requests from one URL to another.
[Application Load Balancer] If the action type is fixed-response , you drop specified client requests and return a custom HTTP response.
Information about an action.
The type of action.
The Amazon Resource Name (ARN) of the target group. Specify only when Type is forward and you want to route to a single target group. To route to one or more target groups, use ForwardConfig instead.

Creates a target group.
To register targets with the target group, use RegisterTargets . To update the health check settings for the target group, use ModifyTargetGroup . To monitor the health of targets in the target group, use DescribeTargetHealth .
To route traffic to the targets in a target group, specify the target group in an action using CreateListener or CreateRule .
To delete a target group, use DeleteTargetGroup .
This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple target groups with the same settings, each call succeeds.
For more information, see Target Groups for Your Application Load Balancers in the Application Load Balancers Guide or Target Groups for Your Network Load Balancers in the Network Load Balancers Guide .

Response Structure
(dict) --
Rules (list) --
Information about the rules.
(dict) --
Information about a rule.
RuleArn (string) --
The Amazon Resource Name (ARN) of the rule.
Priority (string) --
The priority.
Conditions (list) --
The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .
(dict) --
Information about a condition for a rule.
Field (string) --
The field in the HTTP request. The following are the possible values:
Values (list) --
The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.
If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.
If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.
HostHeaderConfig (dict) --
Information for a host header condition. Specify only when Field is host-header .
Values (list) --
One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
PathPatternConfig (dict) --
Information for a path pattern condition. Specify only when Field is path-pattern .
Values (list) --
One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .
HttpHeaderConfig (dict) --
Information for an HTTP header condition. Specify only when Field is http-header .
HttpHeaderName (string) --
The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.
Values (list) --
One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
QueryStringConfig (dict) --
Information for a query string condition. Specify only when Field is query-string .
Values (list) --
One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.
If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
(dict) --
Information about a key/value pair.
Key (string) --
The key. You can omit the key.
Value (string) --
The value.
HttpRequestMethodConfig (dict) --
Information for an HTTP method condition. Specify only when Field is http-request-method .
Values (list) --
The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
SourceIpConfig (dict) --
Information for a source IP condition. Specify only when Field is source-ip .
Values (list) --
One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.
If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .
Actions (list) --
The actions. Each rule must include exactly one of the following types of actions: forward , redirect , or fixed-response , and it must be the last action to be performed.
(dict) --
Information about an action.

[REQUIRED]
The Amazon Resource Name (ARN) of the rule.
The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .
Information about a condition for a rule.
The field in the HTTP request. The following are the possible values:
The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.
If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.
If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.
Information for a host header condition. Specify only when Field is host-header .
One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
Information for a path pattern condition. Specify only when Field is path-pattern .
One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .
Information for an HTTP header condition. Specify only when Field is http-header .
The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.
One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
Information for a query string condition. Specify only when Field is query-string .
One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.
If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
Information about a key/value pair.
The key. You can omit the key.
The value.
Information for an HTTP method condition. Specify only when Field is http-request-method .
The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
Information for a source IP condition. Specify only when Field is source-ip .
One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.
If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .
The actions. Each rule must include exactly one of the following types of actions: forward , fixed-response , or redirect , and it must be the last action to be performed.
If the action type is forward , you specify one or more target groups. The protocol of the target group must be HTTP or HTTPS for an Application Load Balancer. The protocol of the target group must be TCP, TLS, UDP, or TCP_UDP for a Network Load Balancer.
[HTTPS listeners] If the action type is authenticate-oidc , you authenticate users through an identity provider that is OpenID Connect (OIDC) compliant.
[HTTPS listeners] If the action type is authenticate-cognito , you authenticate users through the user pools supported by Amazon Cognito.
[Application Load Balancer] If the action type is redirect , you redirect specified client requests from one URL to another.
[Application Load Balancer] If the action type is fixed-response , you drop specified client requests and return a custom HTTP response.
Information about an action.
The type of action.
The Amazon Resource Name (ARN) of the target group. Specify only when Type is forward and you want to route to a single target group. To route to one or more target groups, use ForwardConfig instead.
[HTTPS listeners] Information about an identity provider that is compliant with OpenID Connect (OIDC). Specify only when Type is authenticate-oidc .
The OIDC issuer identifier of the IdP. This must be a full URL, including the HTTPS protocol, the domain, and the path.
The authorization endpoint of the IdP. This must be a full URL, including the HTTPS protocol, the domain, and the path.
The token endpoint of the IdP. This must be a full URL, including the HTTPS protocol, the domain, and the path.
The user info endpoint of the IdP. This must be a full URL, including the HTTPS protocol, the domain, and the path.
The OAuth 2.0 client identifier.
The OAuth 2.0 client secret. This parameter is required if you are creating a rule. If you are modifying a rule, you can omit this parameter if you set UseExistingClientSecret to true.
The name of the cookie used to maintain session information. The default is AWSELBAuthSessionCookie.
The set of user claims to be requested from the IdP. The default is openid .
To verify which scope values your IdP supports and how to separate multiple values, see the documentation for your IdP.
The maximum duration of the authentication session, in seconds. The default is 604800 seconds (7 days).
The query parameters (up to 10) to include in the redirect request to the authorization endpoint.
The behavior if the user is not authenticated. The following are possible values:
Indicates whether to use the existing client secret when modifying a rule. If you are creating a rule, you can omit this parameter or set it to false.
[HTTPS listeners] Information for using Amazon Cognito to authenticate users. Specify only when Type is authenticate-cognito .
The Amazon Resource Name (ARN) of the Amazon Cognito user pool.
The ID of the Amazon Cognito user pool client.

The query parameters (up to 10) to include in the redirect request to the authorization endpoint.
The behavior if the user is not authenticated. The following are possible values:
The order for the action. This value is required for rules with multiple actions. The action with the lowest value for order is performed first. The last action to be performed must be one of the following types of actions: a forward , fixed-response , or redirect .
[Application Load Balancer] Information for creating a redirect action. Specify only when Type is redirect .
The protocol. You can specify HTTP, HTTPS, or #{protocol}. You can redirect HTTP to HTTP, HTTP to HTTPS, and HTTPS to HTTPS. You cannot redirect HTTPS to HTTP.
The port. You can specify a value from 1 to 65535 or #{port}.
The hostname. This component is not percent-encoded. The hostname can contain #{host}.
The absolute path, starting with the leading "/". This component is not percent-encoded. The path can contain #{host}, #{path}, and #{port}.
The query parameters, URL-encoded when necessary, but not percent-encoded. Do not include the leading "?", as it is automatically added. You can specify any of the reserved keywords.

Registers the specified targets with the specified target group.
If the target is an EC2 instance, it must be in the running state when you register it.
By default, the load balancer routes requests to registered targets using the protocol and port for the target group. Alternatively, you can override the port for a target when you register it. You can register each EC2 instance or IP address with the same target group multiple times using different ports.
With a Network Load Balancer, you cannot register instances by instance ID if they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1, G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these types by IP address.
To remove a target from a target group, use DeregisterTargets .

Information about the rules.
Information about a rule.
The Amazon Resource Name (ARN) of the rule.
The priority.
The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .
Information about a condition for a rule.
The field in the HTTP request. The following are the possible values:
The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.
If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.
If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.
Information for a host header condition. Specify only when Field is host-header .
One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
Information for a path pattern condition. Specify only when Field is path-pattern .
One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .
Information for an HTTP header condition. Specify only when Field is http-header .
The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.
One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
Information for a query string condition. Specify only when Field is query-string .
One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.
If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
Information about a key/value pair.
The key. You can omit the key.
The value.
Information for an HTTP method condition. Specify only when Field is http-request-method .
The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
Information for a source IP condition. Specify only when Field is source-ip .

Response Structure
(dict) --
Rules (list) --
Information about the rules.
(dict) --
Information about a rule.
RuleArn (string) --
The Amazon Resource Name (ARN) of the rule.
Priority (string) --
The priority.
Conditions (list) --
The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .
(dict) --
Information about a condition for a rule.
Field (string) --
The field in the HTTP request. The following are the possible values:
Values (list) --
The condition value. You can use Values if the rule contains only host-header and path-pattern conditions. Otherwise, you can use HostHeaderConfig for host-header conditions and PathPatternConfig for path-pattern conditions.
If Field is host-header , you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.
If Field is path-pattern , you can specify a single path pattern (for example, /img/*). A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.
HostHeaderConfig (dict) --
Information for a host header condition. Specify only when Field is host-header .
Values (list) --
One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
PathPatternConfig (dict) --
Information for a path pattern condition. Specify only when Field is path-pattern .
Values (list) --
One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .
HttpHeaderConfig (dict) --
Information for an HTTP header condition. Specify only when Field is http-header .
HttpHeaderName (string) --
The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.
Values (list) --
One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
QueryStringConfig (dict) --
Information for a query string condition. Specify only when Field is query-string .
Values (list) --
One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.
If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
(dict) --
Information about a key/value pair.
Key (string) --
The key. You can omit the key.
Value (string) --
The value.
HttpRequestMethodConfig (dict) --
Information for an HTTP method condition. Specify only when Field is http-request-method .
Values (list) --
The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
SourceIpConfig (dict) --
Information for a source IP condition. Specify only when Field is source-ip .
Values (list) --
One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.
If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .
Actions (list) --
