Quoting Lucia Di Occhi <saint_lucy@xxxxxxxxxxx>:
I don't see anything with regard to the x-forward-patch being
included in STABLE12. The diff file does not mention anything
either. Is this a distro specific thing?
Lucia:
Squid has several enhancement options that may or may not fit any
particular user, and most (if not all) of them are hosted on a
dedicated squid projects page that used to be at squid.sourceforge.net
using any one of these enhancements to squid may provide additional
functionality that the main squid package is lacking.
check it out.
