JSP Interview Questions and Answers << Previous Question Next Question >> Question: 598 Page Views:  What approaches are used for Session Management in JSP ? Posted By: Avi Date: 17 September 2009 06:24:36 AM Answer: Following approches can be used for Session Management in JSP: 1) Cookies: Cookies are small text files that a web server sends to a browser and that browsers returns the cookie when it visits the same site again. In cookie the information is stored in the form of a name, value pair. 2) URL Rewriting: In URL rewriting we append some extra information on the end of each URL that identifies the session. This URL rewriting can be used with the clients where cookie is disabled. It is a good practice to use URL rewriting. In this session ID information is embedded in the URL, which is recieved by the application through Http GET requests when the client clicks on the links embedded with a page. 3) Hidden form fields: In hidden form fields are html "input" control with type="hidden". The data stored in these fields are included in get or post method, but this information will not be displyed in the page. In this session ID information would be embedded within the form as a hidden field and submitted with the Http POST method. 4) HttpSession object: javax.servlet.http.HttpSession is an interface that provides a way to identify a user across more than one page request or visit to a web site and maintains session data in the site.
