Re: Observing packets in Squid

Hello Michael,

That depends on what you want to filter out.

If you do it in client_side.c you still have an opportunity to use
squids internal error handling to issue a error page.

If you want to sniff out the stream you can do it in http.c, but when
you see something you don't like the only way I've found to interrupt
and reset the browser is my issuing a java redirect to an errorpage.

If you want to intercept things even before all that, I think you want
to do it in comm.c but I've never had a need to look at things that
early on.
