I understand that the Set_Cookie might be causing some caching problems. But I don't understand why "Cache-Control: max-age=0, must-revalidate, proxy-revalidate" would create a problem. The page gets cached by firefox and IE properly. Has this something to do with private vs shared or public caches ? Another question is under what circumstances would squid send a If-None-Match or If-Modified-Since header to the origin server irrespective of the client/browser used to make this request.
