[FIXED] Is the HttpServletRequest-object unique for each request?

Issue

I have implemented with a servlet with below doGet & doPost methods:

        public void doGet(HttpServletRequest request, HttpServletResponse response){
               // code      
            }

        public void doPost(HttpServletRequest request, HttpServletResponse response){
               // code      
            }

My question: Is the HttpServletRequest object in these methods unique for every unique ?

I am using request.setAttribute("att","value"); method. to save some values.

I want to know if I save an attribute in first request, will be it present in the next request object. (Provided both requests are received at almost same time)

Solution

No - its a new request every time - any attributes set in one request, will not be there when the next request comes in.

If you want to set attributes that are persistent across requests, you can use:

request.getServletContext().setAttribute("att","value");
