Headers
import type { Headers } from "https://aws-api.deno.dev/v0.4/services/wafv2.ts?docs=full";Inspect all headers in the web request. You can specify the parts of the headers to inspect and you can narrow the set of headers to inspect by including or excluding specific keys.
This is used to indicate the web request component to inspect, in the "FieldToMatch" specification.
If you want to inspect just the value of a single header, use the SingleHeader FieldToMatch setting instead.
Example JSON: "Headers": { "MatchPattern": { "All": {} }, "MatchScope": "KEY", "OversizeHandling": "MATCH" }
§Properties
The filter to use to identify the subset of headers to inspect in a web request.
You must specify exactly one setting: either All, IncludedHeaders, or ExcludedHeaders.
Example JSON: "MatchPattern": { "ExcludedHeaders": {"KeyToExclude1", "KeyToExclude2"} }
The parts of the headers to match with the rule inspection criteria.
If you specify All, WAF inspects both keys and values.
What WAF should do if the headers of the request are larger than WAF can inspect. WAF does not support inspecting the entire contents of request headers when they exceed 8 KB (8192 bytes) or 200 total headers. The underlying host service forwards a maximum of 200 headers and at most 8 KB of header contents to WAF.
The options for oversize handling are the following:
CONTINUE- Inspect the headers normally, according to the rule inspection criteria.MATCH- Treat the web request as matching the rule statement. WAF applies the rule action to the request.NO_MATCH- Treat the web request as not matching the rule statement.
