If you want to intercept each request before it gets to the Struts
controller servlet (or any other resource in your app), filters are
definitely the way to go. There are some pointers to tutorial information
on the Servlet page at java.sun.com
<http://java.sun.com/products/servlet/>. There's also *lots* of good
tutorial information on web application development in the Web Services
Pack tutorial (start at <http://java.sun.com/webservices/>).
