Description

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 RegexMatchTuple objects (filters) in a RegexMatchSet. For each RegexMatchSetUpdate object, you specify the following values:
  • Whether to insert or delete the object from the array. If you want to change a RegexMatchSetUpdate object, you delete the existing object and add a new one.
  • The part of a web request that you want AWS WAF to inspectupdate, such as a query string or the value of the User-Agent header.
  • The identifier of the pattern (a regular expression) that you want AWS WAF to look for. For more information, see RegexPatternSet.
  • Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.
For example, you can create a RegexPatternSet that matches any requests with User-Agent headers that contain the string 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. Create a RegexMatchSet. For more information, see CreateRegexMatchSet.
  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRegexMatchSet request.
  3. 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 identifier of the RegexPatternSet that contain the regular expression patters 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

-ChangeToken <String>
The value returned by the most recent call to GetChangeToken.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-ClientConfig <AmazonWAFRegionalConfig>
Amazon.PowerShell.Cmdlets.WAFR.AmazonWAFRegionalClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>

-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'ChangeToken'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.WAFRegional.Model.UpdateRegexMatchSetResponse).

Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
