This sounds like you are using a Controller servlet design, in which a front-controller servlet receives the request, examines it, then passes the request along to the proper servlet or JSP. In this case, using an object that implements the javax.servlet.RequestDispatcher interface, as in
RequestDispatcher dispatcher = request.getRequestDispatcher(String path_to_servlet_or_JSP_destination ); ... in your servlet get method, will avoid problems with the "back" button, if I'm understanding your message correctly. you then pass the HTTP request along using the dispatcher.forward( request,response ) method, and it's the destination page that ends up sending the response to the browser, not the Controller servlet. Everything happens in this case on the server side. See for instance http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/RequestDispatche r.html Bruce -----Original Message----- From: Hélder Sousa <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Date: Monday, January 20, 2003 12:53 PM Subject: Servlet question... Hello This is the first mail that I send to the list with an intriguer doubt.. I think :) I have a servlet that is responsable for create several pages depending a parameter that I send. Depending that parameter I create an instance of an object that I need for create the selected page contents (in HTML, of course). The ideia is have some differents java objects that corresponde to the differents pages and the user "enter" in the site for an only "door", the single servlet, using GET METHOD. Until here I don't have any problems.. The main problem is about the browser.. When I "enter" some pages through my servlet and then I make "back" in the browser, it load the page from server again.. For the common pages this isn't a problem, but in my case the objects invoke services in server and delay to much the response to the browser.. My question is: what happens when I click in "back" button? There is a way to make the browser do not load the servlet from server again?
