conn.hostis not equal toHostHTTP header.According to MDN,
Hostheader contains the host and port number of the server to which the request is being sent.On the other side,
conn.hostcontains only the host.Even though you enable
preserve_host_headeroption, theHostheader is not preserved currently.The port number is omitted.
This PR is to fix the problem and preserve original
Hostheader intact.
