How to get the previous page URL from request in servlet after dispatcher.forward(request, response)

Question

I'm using the servlet which redirects me with the help of

dispatcher.forward(request, response);

in the end. But after this I want to get the page(path) from which I was redirected to use it in next servlet command(to go to previous page). How could I get it? Or previous URL is not contained in request parameters and I should add it myself? Will be very grateful for your help.

Answer 1

String referer = request.getHeader("Referer"); response.sendRedirect(referer);

Answer 2

Try using

request.getAttribute("javax.servlet.forward.request_uri")
