Servlets don't cache their output, which is (I think) what you are talking about. It's problematic to keep browsers from caching their images: if you create a new image, you should use a new URL (even if it isn't in a meaningful way, e.g., adding a meaningless get variable onto it). Other caching you notice is probably on the browser end. If you are using Mozilla, I think you have to hit shift to really get it to reload (it's a little stuborn). > 2.

Oh, I always forget the exact format and headers, but it's all the standard ways, mostly setting a header about expiring. There's no Webware specific techniques.
