The FAQ is a bit outdated... This is only true for a brain-damaged
transparent proxy not supporting Host: headers, or when you use old
clients not sending Host: headers.

Does not matter.

--- 1.1.22 and later ---

httpd_accel virtual 80
httpd_accel_uses_host_header on

--- 1.1.21 and earlier ---
httpd_accel 80
httpd_accel_uses_host_header on
(Drawback: Does not support old clients)
apply a small patch available from
somewhere in "old patches" and use 1.1.22 settings above.
use transproxyd in front of Squid.
(Drawback: more processes)
