Amazonka.WAFRegional.UpdateSizeConstraintSet
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 SizeConstraint objects (filters) in a
SizeConstraintSet. For each SizeConstraint object, you specify the
following values:
- Whether to insert or delete the object from the array. If you want
to change a
SizeConstraintSetUpdateobject, you delete the existing object and add a new one. - The part of a web request that you want AWS WAF to evaluate, such as
the length of a query string or the length of the
User-Agentheader. Whether to perform any transformations on the request, such as converting it to lowercase, before checking its length. Note that transformations of the request body are not supported because the AWS resource forwards only the first
8192bytes of your request to AWS WAF.You can only specify a single type of TextTransformation.
- A
ComparisonOperatorused for evaluating the selected part of the request against the specifiedSize, such as equals, greater than, less than, and so on. - The length, in bytes, that you want AWS WAF to watch for in selected part of the request. The length is computed after applying the transformation.
For example, you can add a SizeConstraintSetUpdate object that matches
web requests in which the length of the User-Agent header is greater
than 100 bytes. You can then configure AWS WAF to block those requests.
To create and configure a SizeConstraintSet, perform the following
steps:
- Create a
SizeConstraintSet.For more information, see CreateSizeConstraintSet. - Use GetChangeToken to get the change token that you provide in the
ChangeTokenparameter of anUpdateSizeConstraintSetrequest. - Submit an
UpdateSizeConstraintSetrequest to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value 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.

Create a value of UpdateSizeConstraintSet with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:sizeConstraintSetId:UpdateSizeConstraintSet', updateSizeConstraintSet_sizeConstraintSetId - The SizeConstraintSetId of the SizeConstraintSet that you want to
update. SizeConstraintSetId is returned by CreateSizeConstraintSet and
by ListSizeConstraintSets.
$sel:changeToken:UpdateSizeConstraintSet', updateSizeConstraintSet_changeToken - The value returned by the most recent call to GetChangeToken.
$sel:updates:UpdateSizeConstraintSet', updateSizeConstraintSet_updates - An array of SizeConstraintSetUpdate objects that you want to insert
into or delete from a SizeConstraintSet. For more information, see the
applicable data types:
- SizeConstraintSetUpdate: Contains
ActionandSizeConstraint - SizeConstraint: Contains
