[homeserver] "Host" header is not read

[86667]

We expect "Host" as well as "Pubky-Host" to be valid headers in http requests. However:

curl -i https://homeserver.staging.pubky.app/pub/pubky.app/hello.txt -H "Host: b3p9kmimbq8irxe8hwwg85qbe34r3i6f3fcqw9jo61wsh13eftio" 

returns HTTP/1.1 404 Not Found

Whilst:

curl -i https://homeserver.staging.pubky.app/pub/pubky.app/hello.txt -H "Pubky-Host: b3p9kmimbq8irxe8hwwg85qbe34r3i6f3fcqw9jo61wsh13eftio"

returns HTTP/1.1 200 OK

I've just attempted to reproduce locally and both headers return data. This makes me think that a firewall or load balancer is removing or re-assigning the "Host" header.

Question is - does this even matter? I guess no applications depend on Host since this has only now been identified. Maybe we simply remove "Host" from the code and docs
