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.
Inserts or deletes RegexPatternString
objects in a RegexPatternSet.
For each RegexPatternString
object, you specify the following values:
Whether to insert or delete the RegexPatternString
.
The regular expression pattern that you want to insert or delete. For more information, see RegexPatternSet.
For example, you can create a RegexPatternString
such as B[a@]dB[o0]t
.
AWS WAF will match this RegexPatternString
to:
BadBot
BadB0t
B@dBot
B@dB0t
To create and configure a RegexPatternSet
, perform the following steps:
Create a RegexPatternSet.
For more information, see CreateRegexPatternSet.
Use GetChangeToken to get the change token that you provide in the ChangeToken
parameter of an UpdateRegexPatternSet
request.
Submit an UpdateRegexPatternSet
request to specify the regular expression pattern
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.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginUpdateRegexPatternSet and EndUpdateRegexPatternSet.

WAFInvalidRegexPatternException | The regular expression (regex) you specified in RegexPatternString is invalid. |
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. |
