Subject Re: Possible bug in RequestDispatcher?
Date Mon, 04 Nov 2002 19:41:07 GMT
In Servlet 2.3 (i.e. Tomcat 4.x), filters are *not* invoked on request
dispatcher calls -- only on the original request.  In Servlet 2.4 (i.e.
Tomcat 5.x) you can optionally configure which filters should be used on
forwards, includes, or both, with suitable settings in web.xml.
