http://issues.apache.org/bugzilla/show_bug.cgi?id=39402 Summary: enabling gzip negotiation overwrites existing "vary:" headers Product: Tomcat 5 Version: 5.5.0 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: Connector:HTTP AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] If you have a site that uses "vary:" headers such as "vary: cookie" to distinguish between the cacheability of pages for cookied and non-cookied users this header will get overwritten if you enable gzip negotiation in tomcats server.xml config. If gzip negotiation is enabled it should modify the vary header *not* overwrite it. This is quite bad as enabling gzip in the config can currently cause incorrect files to get cached in browsers/proxies. By the time a developer realises that the gzip functionality is broken in this way, various caches will hold the wrong content possibly for long periods of time even once gzip is turned off again. I suggest putting a warning in the server.xml against using gzip negotiation if you are already using vary headers until this bug gets fixed. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
