browser caching problem

[Thinh Doan <td...@twjconsulting.com>]

If a component of the template on a jsp changes, the browser does not seem
to know the change and presents a cached page (or perhaps I didn't set the
caching properties correctly on the browser).  In some projects, I've seen a
random number as a url parameter (xxx.jsp&rn=12347834...) just to ensure
that the browser does not cache it.  Is there a way to do something like
this (avoiding browser caching) with jsp/struts?

Thank you for your response and have a great weekend.
