It resolves #569
Description
So far, the HTTP host header has been used to determine the hostname that is being accessed. In HTTP/2, this header is not guaranteed to be sent. Instead, the ":authority" pseudo-header field is used. I added a check for that header to make virtual hosts also work with HTTP/2.
Also I found out that the HTTP host header may also contain the port number, so I added a check to remove it if it's there.
How Has This Been Tested?
Not thoroughly, just manually for my usecase, so there may still be problems I didn't consider.
I suppose an automated test would be nice but I'm not sure what's the best way to do this.
