SizeConstraintStatement class
A rule statement that compares a number of bytes against the size of a
request component, using a comparison operator, such as greater than (>)
or less than (<). For example, you can use a size constraint statement to
look for query strings that are longer than 100 bytes.
If you configure AWS WAF to inspect the request body, AWS WAF inspects only the first 8192 bytes (8 KB). If the request body for your web requests never exceeds 8192 bytes, you can create a size constraint condition and block requests that have a request body greater than 8192 bytes.
If you choose URI for the value of Part of the request to filter on, the
slash (/) in the URI counts as one character. For example, the URI
/logo.jpg is nine characters long.

Properties
- comparisonOperator → ComparisonOperator
-
The operator to use to compare the request part to the size setting.
final
- fieldToMatch → FieldToMatch
-
The part of a web request that you want AWS WAF to inspect. For more
information, see FieldToMatch.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- size → int
-
The size, in byte, to compare to the request part, after any
transformations.
final
-
textTransformations
→ List<
TextTransformation> -
Text transformations eliminate some of the unusual formatting that attackers
use in web requests in an effort to bypass detection. If you specify one or
more transformations in a rule statement, AWS WAF performs all
transformations on the content of the request component identified by
FieldToMatch, starting from the lowest priority setting, before inspecting the content for a match.final
