Forms in Rails 2.0

I am using form_for and would like the params of the entered form values
to appear in the url. How can I do this in Rails 2.0 using "form_for"?
Thanks

I believe you need to define a named route so that the URL is formed
how you want in the routes.rb file, under config, associated to
whatever controller/action.
