I have an in house app that has been running for several years, with regular enhancements. Just recently I have noticed that on windows clients, firefox 3.6 is no longer caching any css or js pages. Watching the pages load in firebug, they are all showing as : 304 Not modified but are re-loading anyway. This does not happen with IE or firefox on linux or mac. But firefox seems to be ok with other web sites, so I still have to suspect something with my setup, but don’t really know what to look for. Tonypm
