Subject Re: Proxy Server
Date Tue, 14 Aug 2007 17:45:03 GMT
The stock answer is to setup mod_proxy under Apache and use Apache to 
front-end load all your requests (details located here)
http://tomcat.apache.org/tomcat-5.5-doc/proxy-howto.html

Note that If you have any appreciable amount of static content (watch your 
jmeter perf nosedive) then you will want to look into implementing mod_jk

If you dont want to go thru the complexity of installing yet another system 
then you can use the tried and true request.getHeader as in
String Referer_value = request.getHeader(HTTP_REFERER)
and redirect the request according to some criteria

if Referer_value == "localhost" (this request is for my server so process 
normally)
else
{
        String serverURL = request.getParameter("serverURL");
        String deployuri = request.getParameter("deployuri");

            String redirectURL = serverURL + deployuri;
            response.sendRedirect(redirectURL);
 }

If you've installed Tomcat the example code to retrieve headers is located 
at
http://YourComputer:8080/servlets-examples/reqheaders.html
