Cookies - AWS WAFV2

Cookies

Inspect the cookies in the web request. You can specify the parts of the cookies to inspect and you can narrow the set of cookies to inspect by including or excluding specific keys.

This is used to indicate the web request component to inspect, in the FieldToMatch specification.

Example JSON: "Cookies": { "MatchPattern": { "All": {} }, "MatchScope": "KEY", "OversizeHandling": "MATCH" }

Contents

MatchPattern

The filter to use to identify the subset of cookies to inspect in a web request.

You must specify exactly one setting: either All, IncludedCookies, or ExcludedCookies.

Example JSON: "MatchPattern": { "IncludedCookies": [ "session-id-time", "session-id" ] }

Type: CookieMatchPattern object

Required: Yes

MatchScope

The parts of the cookies to inspect with the rule inspection criteria. If you specify ALL, AWS WAF inspects both keys and values.

All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.

Type: String

Valid Values: ALL | KEY | VALUE

Required: Yes

OversizeHandling

What AWS WAF should do if the cookies of the request are more numerous or larger than AWS WAF can inspect. AWS WAF does not support inspecting the entire contents of request cookies when they exceed 8 KB (8192 bytes) or 200 total cookies. The underlying host service forwards a maximum of 200 cookies and at most 8 KB of cookie contents to AWS WAF.

The options for oversize handling are the following:

  • CONTINUE - Inspect the available cookies normally, according to the rule inspection criteria.

  • MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.

  • NO_MATCH - Treat the web request as not matching the rule statement.

Type: String

Valid Values: CONTINUE | MATCH | NO_MATCH

Required: Yes
