Hello:
I got a problem keeping Internet Explorer from returning values from the cache instead of getting the new values of external files being downloaded.
Sometimes a "refresh" will get IE to get the new values, and somtimes I have to delete all temporary files.
Does anybody know how IE to fix this?
Is there a parameter in IE to say DONOT cache this site?
Is there something I can do to the External Files to enfluence IE?

From my experience with IE this is not possible. I have set every no cache header I could find and I still find situations where IE grabs an old version of the page. Telling it to check every time seems to do nothing either. I have used ethereal(network analyzer) and checked IE5-IE6 and I see the same behavior in all of them. Sometimes it just draws an old version of a page without ever connecting to the server. I just doesn't check if the info has changed and so the headers do nothing it seems. Overall IE has a very broken HTTP implementation and a little reading through the ms knowledge base on it reveals a LOT of issues.It seems to operate on the assumption that the data on pages rarely changes and so makes shortcuts in what it does based on that. I have even had it return an error message from zope up to 2 hours old and clicking in refresh over and over again or shift-refresh did nothing and ethereal showed that the server was not being contacted
