We are using a pretty complicated redirector too, to provide "enhanced proxy
services" (which basically is just what you describe, filtering/blocking
stuff), redirecting "bad" requests to a 1x1 pixel transparent gif.
This approach has several shortcomings though:
1. It only allows matching based on the URL. We don't get to see the
complete request.
2. It is impossible to filter (on) cookies this way.
3. It does NOT allow filtering based on the reply headers send by the
server. "text/html" is almost never an ad, mostly they are "image/*".
(You still could abort transfering the whole file from the server or at
least prevent the client from having to transfer it)
In short, while this approach sort-of works, squid needs a more general
interface for implementing hooks. I don't know if 1.2 is going to be more
modular, but it would be a big improvement.
Maybe one day, squid will link happily with libperl ;-)
