Are you sure it's Tomcat doing the caching? I've found that both Firefox and IE will cache CGI, JSP, servlet, and other dynamic results. This has been true going back to when the old Mozilla 1.x had a preference for *never* caching.
For GET calls were the results underlying content might change and the browser not see it, I've taken to adding a bozo param just so the URL is different: myServlet+"?..."+"&bozo=" + System.currentTimeMillis() On Thu, Aug 5, 2010 at 4:42 PM, swoodbury <swoodb...@att.net> wrote: > > Hi. > > I have a tomcat - struts web application. > > I have a thread which creates a static datafile each night. when the user > accesses the corresponding .do action, that action reads the static file > and > presents formatted output. if the file isn't there for whatever reason, it > creates it dynamically and then presents the formatted output (still by > reading the file it just created). > > My problem is that the nightly re-creation works fine, i can see changes in > the file, and the mod time of the file is updated. but Tomcat is evidently > caching the old contents because the old content is still presented to the > user.
