Having a Hard Time Replacing Default Server Header

Hello;

I’m using uvicorn to front-end an ASGI application of mine and I’m loving it! There is only one slight marring of the beautiful steed which is uvicorn; I have been unable to find a means whereby I can over-ride the sending of the Server: uvicorn header on all outbound responses.

When using HTTP1.1 as the transport protocol, I see in the uvicorn.protocols.http.h11_impl module a _get_default_headers function. I can see that this in turn gets called by H11Protocol#tick, which overrides whatever value that the global DEFAULT_HEADERS variable holds, which in turn is what gets augmented to the headers of every outbound request in the RequestResponseCycle#send method.

Is there a strong reason for this? If not, is there any desire with the existing devs to enable this to be disabled/changed? Or, is there a desired approach that someone else should take if they would wish to introduce a PR that would change this behaviour?

Yup - it’d be available as part of the Config
