Container for the parameters to the UpdateSizeConstraintSet operation.
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 SizeConstraintSetUpdate
object, 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-Agent
header.
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 8192
bytes of your
request to AWS WAF.
You can only specify a single type of TextTransformation.
A ComparisonOperator
used for evaluating the selected part of the request against
the specified Size
, 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 ChangeToken
parameter of an UpdateSizeConstraintSet
request.
Submit an UpdateSizeConstraintSet
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
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.
