That is NOT how Vary works. Go read the HTTP spec. If your content changes based on a header, then you must report that header in Vary for ALL requests. Otherwise, a cache would take the request that it got for a client that didn't have support gzip and send it to browsers that do support gzip, negating the benefit of gzip. I also showed you an easy way to work around the problem if you don't care about incorrect responses from caches. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
