As far as I have understood RFC2616 14.9.1 and 14.9.2, no-cache is supposed to prevent content from being served from cache without revalidation, and no-store forbids storing content altogether. Tests I made with Apache 2.0.49 and 2.0.54 show that Apache gladly serves contents containing "Cache-Control: no-cache" in the response header, from cache without revalidation. On the other hand, if the response contains "Cache-Control: no-store", the response is not cached. I submit that the CACHE_OUT filter should not be run if the cached headers contain "Cache-Control: no-cache". Any thoughts? -ascs --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
