servlet URL question

[Buk Lau]

When submitting a form to a servlet, I process the input parameters and then use:
rd = getServletContext().getRequestDispatcher(URL);
rd.forward(request, response);
to forward to the appropriate jsp page.
I notice that other websites (in general) have the parameter values in the URL, like www.dictionary.com:
http://dictionary.reference.com/search?q=servlet
I am using Tomcat 4.1.29 and it doens't do that. Does Tomcat have a setting to turn this on? If so, why would I want to turn it on (and why would I not want to use it?
Thanks in advance,
Buk

Has nothing to do with a Tomcat setting. It has to do with the method by which the form is posted. A method of POST will pass the params as part of the request; a method of GET will pass in the query string portion of the URL.
