For the record, collapsed forwarding collapses requests _before_ there is any response [header], not after the "first" request got the object [body]. Once there is a response [header], the usual caching code path kicks in and no collapsing is needed. Cache hits on that "usual caching code path" read from a "public" cache entry. Normally, those public entries are created when Squid receives a response [header]. Collapsed forwarding creates that entry before Squids gets the response [header], and, hence, before Squid can know for sure whether the response is going to be cachable, with all the risks that entails. Please do not misinterpret my email as a recommendation to give (or not to give) collapsed forwarding a try. I have _not_ analyzed the problems discussed on this thread. I just wanted to correct the description above. Nothing more.
