Hi, I'm planning to use squid to cache content from a content-rewriting proxy (running apache). The proxy sucks content from a live site and replaces specific text strings. So, http://proxy.example.com/?id=12345 might map to the site http://squid-cache.org replacing all instances of the word "squid" with "foobar". I want squid to cache this. Is it possible to manually expire content in the squid cache when changes are made to the content-rewriting in the proxy? Basically, I'd like to be able to say something like: Expire all content containing the query string "id=12345" Thanks for any suggestions. R.
