AHA! That worked like gold. Thanks for the info! I didn't realize that Tomcat's Response was a superclass of HttpServletResponse. One thing I did note though, is that one can't invoke the next valve in the chain after sending a redirect (as far as I can tell). I suppose this just means that a valve that behaves in such a manner must be the last one in the chain or must break out of the chain midway by simply returning. Again, thanks.
