Hi there, We get quite a few questions revolving around modifying HTTP messages that Squid proxies. A typical answer is to use ICAP, but there are many options to consider and it is tiresome to describe them all in every thread on the subject.
The following wiki page is meant to answer most of the questions related to content capture and adaptation. If there are no better ideas, I plan to link it from the FAQ. Please review: http://wiki.squid-cache.org/SquidFaq/ContentAdaptation It would be nice to add more information about header manipulation hacks, perhaps at least as links to squid-dev emails describing the right locations to do that. Thank you, Alex.
