Hello there,
I'm using squid transparent proxy for caching and I have also youtube
caching done with url_rewrite and apache script running on same
machine as
squid.
It was all working fine, until I decided to go with TPROXY, as it has
many
benefits. When I implemented the tproxy rules in iptables, everything
continued to work except the playing of youtube videos - where the
url_rewriter and the apache script come into play. The url_rewriter
redirects the youtube requests to a local .php script working on the
Apache
(on same machine)
I think it has something to do with how squid communicates with the
local
apache process (where the software for youtube caching works) and
somehow
the tproxy is screwing this up, because after implementing the tproxy
the
requests to the Apache are sent with the USER-IP (previous without
tproxy,
it was with SQUID-IP) and the reply from the apache script probably
goes
directly the user, instead of returning back through the squid
process.
Have you verified that Apache is actually getting the request? Traffic
from a globally routable IP to/from localhost is often prohibited by the
kernel or even hardware.
