But what I dont understand is why IE doesnt send any If-Modified-Since header? Shouldnt it always do that if the settings are not set to never update cached files?
Browser dont spontaneously generate If-Modified-Since - only if you include a Last-Modified header in the original response (Im not entirely sure whether or not they are allowed to) Note that Brian was observing that IE was not sending any request to the server - any request (even one that includes cache control headers) is going to involve a performance hit. Brian: could you repeat your test including the header cache-control: must-revalidate This certainly *should* have the desired effect of not letting IE display stale data. Ive covered the use of this header in some detail in a recent HowTo: http://www.zope.org/Members/htrd/howto/caching Toby Dickenson tdickenson@geminidataloggers.com
