Hi all !

I am using the following code....to do some validation for user authentication.

/construct the requested path
                HttpUtils util=new HttpUtils();
                LastUrl=new StringBuffer("");
                LastUrl=util.getRequestURL(request);
                LastUrl.append("?" + request.getQueryString());
                session.putValue("LastUrl",LastUrl.toString());

// check for user authentication first
checkUser(); ( this method returns boolean valid

// Get the request-dispatcher, to send an order-summary to the client
RequestDispatcher userForward = getServletContext().getRequestDispatcher("/Login.jrun");

                // Have the servlet summarize the order; skip summary on error.
                   if (userForward != null) {
                      try {
                          userForward.include(request, response);
                      } catch (IOException e) {
                      } catch (ServletException e) {
                      }
                   }
                }

From the Login.jrun.In the doPost method I send out the foolowing htm code

                if(valid) {
                          loginOut.write("<meta http-equiv=\"refresh\" content=\"4;" + (String)session.getValue("LastUrl") + "\">");
                          loginOut.newLine();
                }

But after 4 seconds, I get the same Login.jrun page....What is wrong here ?

I tired to print the value for (String)session.getValue("LastUrl") and it is what i want..but it does not appear so !

Second how can i specify no-cache...!

Thanks all !

Gautam
