RE: Rewriting URLs in Tomcat
Hi, I wrote Tomcat's Balancer webapp partially to address this need. Check it out.

Re: Rewriting URLs in Tomcat
sendRedirect(...) tells the browser to use a resource in a different location. That location can be same webapp, different webapp, different server. forward(...) is for the same server only. In context: servletContext.getRequestDispatcher(path).forward(...); Out of context: servletContext.getContext(foreignContextName).getRequestDispatcher(path).forward(...); For forwarding to a different context you have to have the relevant permissions or the servletContext.getContext(foreignContextName) call will return null. In tomcat the context doing the forwarding has to be marked as crossContext: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/context.html Jon PS the chained invocations above are illustrative only, not as I would normally code it ;) Jacob Weber wrote: Tim Funk <[EMAIL PROTECTED]> wrote: At http://funkman.home.comcast.net/ I have a project called ServletUtils.

Re: Rewriting URLs in Tomcat
At http://funkman.home.comcast.net/ I have a project called ServletUtils. You can use either RedirectFilter or ForwardFilter. They both can use regex's. -Tim Jacob Weber wrote: Is it possible to have Tomcat interpret one URL, e.g. http://www.mysite.com/dir/dir/file to really load another one, e.g. http://www.mysite.com/otherdir/otherfile.do I think Apache can do this with mod_rewrite; is there a Tomcat equivalent?

Rewriting URLs in Tomcat
Is it possible to have Tomcat interpret one URL, e.g. http://www.mysite.com/dir/dir/file to really load another one, e.g. http://www.mysite.com/otherdir/otherfile.do I think Apache can do this with mod_rewrite; is there a Tomcat equivalent?
