I am working on converting the functionality of some JSP pages to GWT. I noticed that javax.servlet.http.HttpServletRequest request is an implied object in JSP, and one can obtain the client's refresh count by calling request.getParameter("refreshCount"). I noticed that one can also access this request object in GWT in the service impl...

I've been looking into IntelliJ's advanced features, specifically its on-the-fly CSS validation (their site says that it can find "Unused CSS class definitions") to help us clean up our massive CSS files in our hundreds of JSP pages.

Is there a way to get the URI of a JSP that sent a particular GET/POST request to a Servlet? I know of the request.getRequestURI() function within a Servlet, but that is just returning the URI of the Servlet itself.
