This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates a RegexMatchSet. You then use UpdateRegexMatchSet to identify the part of a web request that you want AWS WAF to inspect, such as the values of the User-Agent header or the query string. For example, you can create a RegexMatchSet that contains a RegexMatchTuple that looks for any requests with User-Agent headers that match a RegexPatternSet with pattern B[a@]dB[o0]t. You can then configure AWS WAF to reject those requests.

To create and configure a RegexMatchSet, perform the following steps:

  1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateRegexMatchSet request.

  2. Submit a CreateRegexMatchSet request.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRegexMatchSet request.

  4. Submit an UpdateRegexMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value, using a RegexPatternSet, that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Parameters:

Raises:

  • WAFDisallowedNameException –

    The name specified is invalid.

  • WAFInternalErrorException –

    The operation failed because of a system problem, even though the request was valid. Retry your request.

  • WAFLimitsExceededException –

    The operation exceeds a resource limit, for example, the maximum number of WebACL objects that you can create for an AWS account. For more information, see Limits in the AWS WAF Developer Guide.

  • WAFStaleDataException –

    The operation failed because you tried to create, update, or delete an object by using a change token that has already been used.

  • UnknownServiceError –

    The service returned an error code this client does not model.
