Yeps, I tried 'curl http://195.159.151.136 -H 'Host: www.tromsø.no' and it
seemed to confuse the server (based on the message the server responds with).

Yes.

Yes. It always points to somewhere within conn->gname[].

We should rename and cleanup the use of the 'name', 'gname' and 'hostname'
fields. gname[] is basicly the buffer storage area, while 'name' and
'hostname' are pointers within that area and both are used in a mixed fashion
when a pointer to the host name is wanted.

It might be useful to store the original input host name as well as the newly
ACE converted one, if nothing else so for info/debug purposes.
