RE: Strange caching issue
This is a good idea and something we have done in the past when the headers did not seem to be working. Just do something like ?id=#randrange(1-1)# to the end of your url's.

This is so weird ... even if I hard code META HTTP-EQUIV info in the html header, it isn't working. Even checked OS, versions, service packs, etc. and no luck.

Re: Strange caching issue
Chris, IIS is set to cache files, but that is the case on both servers. Even when I set the IIS on the production server to expire templates immediately, it is still caching them.

And ... to raise the frustration level a WHOLE lot more ... the files are being cached on only one cluster member. So caching is being prevented on our development server and cluster member #2, but not cluster member #1. I need a drink ...
