RE: Servlet gateway to legacy cgi application
Steve, I've developed servlet-based webapps for several years, I've written servlet filters and implemented many various types of authentication mechanisms, and I've also done request forwarding within an application. I was hoping to implement something similar to request forwarding, but according to Sun, Requests may be forwarded only to components within the same application context root, never between applications. I have to think however that there must be a way to accomplish this. This need has never arisen for me either, so I would not be surprised to find there may be something within the servlet API or within the Tomcat container itself which with I am not familiar. Any thoughts?

RE: Servlet gateway to legacy cgi application
The only issue I can see that he will have is the path in web.xml with
CGIServlet. I have to move all cgi scripts to a directory under my
${catalina_home}/webapps/${host}

RE: Servlet gateway to legacy cgi application
I initially looked at CGIServlet, but I run the Apache http server, rather than using Tomcat's implementation. I also need to implement my own functionality (primarily for user authentication). But yes, this is close to what I'm after. I'm sure I can roll my own, but it would be nice to find an existing solution. I just googled cgiservlet, and this may yield something useful. I will let you know.
