Hello, I'd like to do this: Set Expires and Cache-control headers to specific values on a resource when the response code is 200. Set those headers to different values when the response code is XXX (but not 200). The documentation for mod_expires and mod_headers does not suggest that this is possible; these modules allow configuration according to file matching and mime type, but not response code. The background: With the release of Firefox 5, that browser is now adhering to the HTTP/1.1 specification, which instructs clients to cache "redirect" responses (302, 307, etc.) according to Expires and Cache-control headers. Apparently, using Apache, this means you cannot configure a particular type of resource to be cached by the client if you routinely expect requests for that resource to be "temporarily" redirected. Thanks for the help, Michael --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
