Re: Possible to forward a request to another server?
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. http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/ajp.html Wendell Holmes wrote: Is it possible to forward a request from one Tomcat server to another?

RE: Possible to forward a request to another server?
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 client (along with the address to redirect to), and the client (read: the browser) calls the new address, hence it can be any address you want.

Re: Possible to forward a request to another server?
Look at JSTL's 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" %>
http://otherserver${pageContext.request.requestURI}"/>
--
Then in web.xml:
fever
/WEB-INF/cowbell.jsp
fever

RE: Possible to forward a request to another server?
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 route across the firewall.

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.
