Actually I don't think that this will work. Here is why:
The client makes an HTTP request to the servlet which then uses the
RequestDispatcher to Forward the request to the jsp page. Because he is using the
request dispatcher and not response.sendRedirect() there is no response back to the
client from the servlet. This means that the header that the jsp has access to is
the same header that the servlet had access to (only one HTTP request means only
one HTTP header). Thus request.getHeader("referer") will return the URI of the page
that referred the client to the servlet.
Why don't you want to set an attribute?
