What is unix socket?
for more information visit here
For supporting unix socket url has to be encoded to some thing like this
http+unix://%2Fvar%2Frun%2Fdocker.sock
--^----------------^-------------------
protocal path (actual path is /var/run/docker.sock, slashes are encoded to set in hostname)
protocal has to be http+unix
hostname has to be urlencoded or replace / with %2F (this is requried as dothttp has to figure out url path, having both same confuses)
