Interface CfnRuleGroup.HeadersProperty

All Known Implementing Classes:

CfnRuleGroup.HeadersProperty.Jsii$Proxy

Enclosing class:

CfnRuleGroup

public static interface CfnRuleGroup.HeadersProperty

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" }

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.wafv2.*;
 Object all;
 HeadersProperty headersProperty = HeadersProperty.builder()
         .matchPattern(HeaderMatchPatternProperty.builder()
                 .all(all)
                 .excludedHeaders(List.of("excludedHeaders"))
                 .includedHeaders(List.of("includedHeaders"))
                 .build())
         .matchScope("matchScope")
         .oversizeHandling("oversizeHandling")
         .build();

Method Detail

getMatchPattern

java.lang.Object getMatchPattern()

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"} }

getMatchScope

java.lang.String getMatchScope()

The parts of the headers to match with the rule inspection criteria.

If you specify All , AWS WAF inspects both keys and values.

getOversizeHandling

java.lang.String getOversizeHandling()

What AWS WAF should do if the headers of the request are larger than AWS WAF can inspect.

AWS 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 AWS 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. AWS WAF applies the rule action to the request.
• NO_MATCH - Treat the web request as not matching the rule statement.

builder

static CfnRuleGroup.HeadersProperty.Builder builder()

Returns:

a CfnRuleGroup.HeadersProperty.Builder of CfnRuleGroup.HeadersProperty
