If you are using a Servlet 2.3 compliant application server, you could write a filter that does this automatically for you and apply the filter to the action servlet.

I want to try this out. But first a couple of questions. I have not extended ActionServlet in my webapp, so I want to ask some advice on how to do this and how to adjust the web.xml file. In regards to extending ActionServlet do I something like public final class MyActionServlet extends ActionServlet { } is the only only function I have to override the perform() method? Also, once I have done this, do I change my web.xml file so the line <servlet-class>org.apache.struts.action.ActionServlet</servlet-class> becomes <servlet-class>org.apache.struts.action.MyActionServlet</servlet-class> Is there any examples anywhere which has in it an extended ActionServlet? Thanks for your help.
