Get jsp content after forward

How can I get content of a jsp page, after servlet made a forward. At them moment I'm trying the following:

request.getRequestDispatcher(DESTINATION_PAGE).forward(request, response);
URL teamsURL = new URL(request.getScheme(), request.getServerName(), request.getServerPort(), request.getContextPath() + DESTINATION_PAGE);
URLConnection teamsCon = teamsURL.openConnection();
String fileName = request.getServletContext().getRealPath("/") + System.currentTimeMillis() + ".html";
System.out.println(fileName);
try (BufferedReader in = new BufferedReader(new InputStreamReader(teamsCon.getInputStream()));
     PrintWriter out = new PrintWriter(fileName)) {
    String inputLine = null;
    while ((inputLine = in.readLine()) != null) {
        out.println(inputLine);
    }
}

I get the html with empty divs. But, I want the same page I see in browser.

Sorry for messy post, ask for what info you need, I'll update my post accordingly.

If you're trying to get the response body after you've written it, you'll need to use a custom HttpServletResponse wrapper that keeps track of what was written to the OutputStream directly or with the Writer.

You will do this in a servlet Filter after chain.doFilter(request, yourResponseWrapper) returns. A simple example can be found here.
