Description

I was trying to communicate with a local domain socket that accepts HTTP, which I'm currently doing like so:

docker = connect("/var/run/docker.sock")
write(docker, """
    GET /info HTTP/1.1
    Host: localhost
    Accept: application/json


    """)
@show read(docker, String)
close(docker)

That doesn't really work with HTTP.jl right now, the connection layer doesn't support these sockets, and there isn't a way to separate the path to the socket from the path to request. One interesting approach by https://github.com/msabramo/requests-unixsocket is using the following URI format: http+unix://%2Fvar%2Frun%2Fdocker.sock/info.

Research direction
Review the issue discussion and the current HTTP.jl connection layer (likely in src/connection.jl or similar). Investigate the URI format proposal 'http+unix://%2Fvar%2Frun%2Fdocker.sock/info' and how similar libraries implement support for domain sockets. Check the linked PRs or comments for any prior attempts. After understanding the architecture, propose a design for extending the connection layer to handle unix sockets and implementing the custom URI scheme.
