Joshua, I thought this was working but it is not. This is my sinario: 1) I have a Java servlet that serves up some content. I put a display in the code so I can confirm when it gets called. I also put some code in the servlet to display header parameters that it receives. 2) I clear my disk cache for apache. 3) I restart apache. 4) I hit the servlet through a browser. The log file shows that it was hit. I also notice that there is files in the apache disk cache. 5) I then hit the servlet again through a browser. Nothing comes through the log file. So the servlet never received the request but the page came up. So apache is caching the file. 6) I now trigger another servlet that sends the same URL that I put manually into the browser. This request has the parameter "Cache-Control: max-age=0" added to the header. The servlet I have been talking to shows that it receives a request. The header shows the following name value pairs: header name=Cache-Control header value=max-age=0 header name=pragma header value=no-cache header name=user-agent header value=Java/1.6.0_02 header name=host header value=qa.webtools.uiuc.edu header name=accept header value=text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 header name=connection header value=keep-alive header name=content-length header value=0 When I go to the original servlet again I find the content is still the cached content. It is as though the disk cache module let my request go on through but it did not delete/refresh the data. What should I do?

Just make an HTTP request to the server for the targeted URL with a "Cache-Control: max-age=0" header.
