The vary header includes all sessions IDs used by application, so it's not a problem at all. I just have found the problem: by default, Squid doesn't cache any QUERY string due to an ACL definition. Cocoon always use query strings so, by ACL, is never cached. The solution is as simple as comment that no_cache ACL referenced to QUERY and all works perfectly. Thanks for all. Javier Sianes
