I think you'll need to upgrade to squid-2.4. That version has
this option:

# TAG: httpd_accel_single_host on|off
# If you are running Squid as a accelerator and have a single backend
# server then set this to on. This causes Squid to forward the request
# to this server irregardles of what any redirectors or Host headers
# says.
