public static enum HttpProtocolOptions.HeadersWithUnderscoresAction extends java.lang.Enum<HttpProtocolOptions.HeadersWithUnderscoresAction> implements com.google.protobuf.ProtocolMessageEnum
Action to take when Envoy receives client request with header names containing underscore characters. Underscore character is allowed in header names by the RFC-7230 and this behavior is implemented as a security measure due to systems that treat '_' and '-' as interchangeable. Envoy by default allows client request headers with underscore characters.

ALLOW
public static final HttpProtocolOptions.HeadersWithUnderscoresAction ALLOW
Allow headers with underscores. This is the default behavior.
ALLOW = 0;
-
REJECT_REQUEST
public static final HttpProtocolOptions.HeadersWithUnderscoresAction REJECT_REQUEST
Reject client request. HTTP/1 requests are rejected with the 400 status. HTTP/2 requests end with the stream reset. The "httpN.requests_rejected_with_underscores_in_headers" counter is incremented for each rejected request.
REJECT_REQUEST = 1;
-
DROP_HEADER
public static final HttpProtocolOptions.HeadersWithUnderscoresAction DROP_HEADER
Drop the client header with name containing underscores. The header is dropped before the filter chain is invoked and as such filters will not see dropped headers. The "httpN.dropped_headers_with_underscores" is incremented for each dropped header.
DROP_HEADER = 2;
-
UNRECOGNIZED
public static final HttpProtocolOptions.HeadersWithUnderscoresAction UNRECOGNIZED
