Localhost and http request dilemma!

Question

Right I have 2 web app servers, one running on serverA from machine1 and one running on serverB from machine2.
OK, what I want to be able to do is from machine1 open a browser to a webpage running on serverB/page1.jsp.
From page1.jsp I want to make an http request to "localhost/page2.jsp" which is running on ServerA on machine1 and NOT on the same webserver as page1.jsp.
Now because each machine sees itself as localhost, when I use "localhost/page2.jsp" instead of making a request to "serverA/page2.jsp", it is trying to make a request to ServerB.page2jsp.
Now I cant just replace "localhost" with "ServerA" due to security restrictions of my web application. So far what I've tried is putting this javascript within page1.jsp:
    <%
            URL url = new URL("http://localhost:6080/page2.jsp");
            HttpURLConnection httpConnection = (HttpURLConnection) url.openConnection();
            httpConnection.setRequestMethod("GET");
            httpConnection.setDoOutput(true);
            httpConnection.connect();
            InputStream in = httpConnection.getInputStream();
            BufferedInputStream buffer = new BufferedInputStream(in);
            for (;;) {
                int data = buffer.read();
                // Check for EOF
                if (data == -1) {
                    break;
                } else {
                    out.print((char) data);
                httpConnection.disconnect();
    %>Any thoughts or ideas are gladly appreciated, or if I'm goign about this all wrong let me know!

What security is being restricted with this design?You can only connect to the web server by using "localhost" and not using its real host name or ip address.
So for example I want a web browser running on a windows machine to access page1.jsp from a linux machine running a web server and within page1 I want to make a http request to page2 running on a webserver on the windows machine and for example return the html from page2 into page1.
So far I've tried the scriplet in the above code which makes a call to localhost, but it makes a call to the wrong localhost, rather than localhost being the machine im running the browser in, localhost is machine that the web page is running on. I've also thought about using iframes, any thoughts on this approach?
