I am working on a webbased application which has JSP and servlets. In my application, I am binding some objects to sessions like the following code --

HttpSession session = p_req.getSession();        
 session.setAttribute(DOWNLOAD_With_WARNINGS, downloadMap);

Later I am retrieving them using session.getAttribute. I would like to know if every time I open a new browser does it open a new HTTP session. Because , if I do a setAttribute with some value in one browser instance, that change is visible when I do a getAttribute using the other browser instance.
