We have a similar problem, but with another twist. We don't want proxies along the way to cache pages, since their content is dynamically created. So we set the cache-related http headers, and in addition add a parameter to the URL (pdc=clock tick at the time of url creation) (pdc is an acronym for "please don't cache"). This works well most of the time, but from time to time we get a cached page nevertheless. We see this as the accompanying cookie identifies someone else's session, and the users experiencing this have to log on to our site again. And again. Etc. I'd really appreciate any light shed on the topic "proxy servers and cookies". I've also noticed a funny http response header that I suspect our netscape servers to add every once in a while, but I don't recognize the header itself nor its semantics. Any suggestions welcome! Cache-control: no-cache="set-cookie, set-cookie2"

I would try using the headers with different values to see if it makes any effect: response.setHeader("Cache-Control","no-cache"); response.setDateHeader ("Expires", 0); Those lines should prevent caching at the proxy server.

We have a JSP Application running on JRun 3.1. This is a Local Intranet Application. I have a hidden field in form <input type="hidden" name="mode" value="0"> When I submit the form I get following strage results. Situation 1. Bypass the Proxy Server First time I get the value of mode. If I use back button of browser and submit again the parameter becomes null. Situation 2. Go thru proxy server I always gets the value irrespective of first time or second time. Since going thru proxy slows down the access we do not want to use that. Could anyone throw some light to this strage problem. Thanks in Advance...
