Proxy Server 2007-08-14 - By Martin Gainty

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 (See http://cat-5.ora-code.com).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
