Rick, don't be so precious! Incidentally, what is the Servlet text you currently have in your possession? I have two: 'Java Servlet Programming', and 'Java Servlet Programming Bible' (can't recall authors at present - they're at home).

Maybe before you make a vague suggestion like "get a book" , you may want to qualify about whether or not the desired result is possible and suggest an appropriate resource that may actually contain said information( book title, etc,). Its always nice to try something a little different and be demoted to idiot status with the statment , "get a book" Does anyone have an useful information -Rick -----Original Message----- From: Tim Funk [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 18, 2003 11:02 AM To: Tomcat Users List Subject: Re: Extending HttpServletRequest / HttpServletResponse ??? I'd recommend getting a Serlvet programming book and optionally a JSP book. They will come in very handy for these questions. valve - Tomcat specific filter - "Like" a valve but portable across other servlet containers because its part of the serlvet specification. requests/response can be wrapped by the Servlet wrapper classes which are part of the Servlet API. A book will really help clear the specifics up of why and when to use them. Never ever use catalina classes directly unless: - You really need to - You really know why you are using them - You really need to -Tim Gavin, Rick wrote: > Thanks Bill, > Does anyone have some docs about using this feature?
