Make your pages adhere to the RFC spec for caching. Use cache-control headers such as "no-cache" or "private" to ensure cache is revalidated against the source. You haven't provided any details on the type of page you're calling from "whatever" but likely the resource is considered cacheable and the browser doesn't need to revalidate against httpd. There is a pretty good overview of browser caching here: http://www.mnot.net/cache_docs/ James Rapp -----Original Message----- From: Ben Johnson [mailto:b...@indietorrent.org] Sent: Saturday, August 18, 2012 9:51 AM To: users@httpd.apache.org Subject: Re: [users@httpd] mod_rewrite And Browser Caching On 8/18/2012 11:30 AM, sebb wrote: > On 18 August 2012 15:55, Drew Tomlinson <d...@mykitchentable.net> wrote: >> I've been working at this for days and couldn't figure out why a mod_rewrite >> rule wasn't working.
