      Case 1. Servlet request forward.
      Create servlet filter.

      import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;

@WebFilter(servletNames = "Faces Servlet")
public class Forwarder implements Filter {

	@Override
	public void init(FilterConfig filterConfig) throws ServletException {
	}

	@Override
	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,
			ServletException {
		if (((HttpServletRequest) request).getRequestURI().endsWith("forward-me.xhtml")) {
			RequestDispatcher dispatcher = request
					.getRequestDispatcher("forward-target.xhtml");
			dispatcher.forward(request, response);
		} else {
			chain.doFilter(request, response);
		}
	}

	@Override
	public void destroy() {
	}

}

      Request "forward-me.xhtml". Observe "GET forward-target.xhtml" being written to access log.

      Case 2. Servler error handling.
      Create error page, register it in web.xml.

      <error-page>
	<location>/error.xhtml</location>
</error-page>

      Request some page, that throws a error on GET. Observe "GET error.xhtml" being written to access log.

      Noticed this happening in two cases.

      1. Servlet request forward (javax.servlet.DispatcherType.FORWARD).
      2. Servlet error handling (javax.servlet.DispatcherType.ERROR).

      In both cases %r and %U result in a rewritten URL being written to access log, not the original. This was not the case in JBoss Web at least for forwarding (didn't use servlet error handling then). The rewritten URL could be useful too, but it should be available as a separate token.

      Didn't test javax.servlet.DispatcherType.INCLUDE.
