Thanks again.
You need to modify the headers and body of selected HTTP responses. It is not trivial to do this right, but it is doable, and there are deployed Squid proxies doing that. For a high-level overview, you may want to start at http://wiki.squid-cache.org/SquidFaq/ContentAdaptation I believe Squid treats adapted pages as if they come from the origin server. Thus, Squid should cache cachable adapted responses. How much additional control you get via Squid ACLs, I do not know. I would not be surprised if some ACLs are not checked for ICAP responses. The original response will not be cached if you modify it. Squid ICAP and eCAP code only support pre-cache response modification. HTH, Alex.
