headerName property
The name of the HTTP header to match.
For matching against the HTTP request's authority, use a headerMatch with the header name ":authority".
For matching a request's method, use the headerName ":method".
When the URL map is bound to a target gRPC proxy that has
the validateForProxyless field set to true, only
non-binary
user-specified custom metadata and the content-type header are
supported.
The following transport-level headers cannot be used in header matching
rules:
:authority, :method, :path, :scheme, user-agent,
accept-encoding, content-encoding, grpc-accept-encoding,
grpc-encoding, grpc-previous-rpc-attempts, grpc-tags-bin,
grpc-timeout and grpc-trace-bin.
