Is it possible to forward a request from one Tomcat server to another? I
looked at the API's and it seems to say the resource must be located on the
same server and in the same servlet context. I'm needing to have some way
to forward http requests from an external IIS web server to an internal
Hi,
Like HttpServletResponse#sendRedirect? It's not like a forward in that
the client URL changes, but it does pass the request to another server.
Beyond that, you COULD write something that'd wrap the request, invoke
another server to handle it, and stream the response to your own client.

Thanks, Yoav.
I will try to write something to wrap the request. The streaming back part
answers my question about how to handle the response.
I could simply use IIS to redirect the original request, but the server
address would be unreachable for the client as only the web server would
have a
Look at JSTL's c:import tag. If you don't do posts (or images) - it might
be enough of a quick kludge.
For example, call this page cowbell.jsp:
--
%@ taglib uri=http://java.sun.com/jstl/core/c.tld; prefix=c %
c:import url=http://otherserver${pageContext.request.requestURI}/
--
Then in web.xml:
In simplest terms, a response forward sends control to something in the same
context and the forwarded, a response rediect can go to something outside
the context. The technical difference is that a forward is done entirely on
the server, wheras a redirect sends the redirect command to the
You may want to look at plugging it in using an AJP connector, which is
a webserver plugin which talks to your Tomcat JVM across TCP/IP using a
proprietary protocol. I've only done this with Apache, but they
apparently exist for IIS and iPlanet too.
