Should allow colon in metadata keys for HTTP/2 pseudo headers? about grpc-node

[mng12689]

I also just realized that gRPC metadata is not the same thing as HTTP/2 headers (and I'm guessing aren't implemented as such), in which case this issue is probably not relevant. Is there a way to modify the underlying HTTP/2 headers for a gRPC request?

You can't directly set the :authority header because gRPC internally handles HTTP2 protocol pseudo-headers. You can modify the authority for an entire client by setting the option "grpc.default_authority" at client construction, and I think you can set it for a single call by passing it in the host key in the options call argument.

gRPC metadata does in fact correspond directly to HTTP2 headers.

@murgatroid99 It works fine! Thanks
