URI issue

[beef9999]

This program is good as a independent software, but unfortunately, doesn't meet the RFC standard.

https://www.ietf.org/rfc/rfc3986.txt
The URI's syntax is ^(([^:/?#]+):)?(//([^/?#]))?([^?#])(?([^#]))?(#(.))?
Which means ':' cannot appear between hostname and location.

I think the proper syntax is http+unix://%2Fpath%2Fto%2Fsocket.sock/some_location.

Of course this issue is still under debate on the Internet.
