[Bug 640511] [NEW] squid in lucid adds bogus port number to Host: line if one isn't provided (in original or via vport=)

[James Troup]

Public bug reported:

Binary package hint: squid

After upgrading to lucid we noticed that squid was adding the
http_port port number to any Host: line that came in without port
number.  Our setup looks (something like) this:

 SSL termination -> squids -> backends

Once these squids beceame lucid, the backends started seeing 'Host:
example.com:3128' instead of 'Host: example.com' (what the original
requestor actually sent).  This is a) totally bogus and b) breaks some
of our backends (they 500 if asked to process a request which has a
host line with a port number they're not listening on).  We're able to
work around this for some hosts by explicitly specifying 'vport=80' as
an option to 'http_port' but this doesn't work when we have multiple
backends on the same IP but different ports.
