Hi Anju!
U use URL Rewriting,
If the user's browser does not support cookies and the user clicks on an un-rewritten URL, the user's session is lost. The servlet contacted through that link creates a new session, but the new session does not have the data associated with the previous session. Once a servlet loses the session data, the data is lost for all servlets that share the session. You should consistently use URL rewriting if your servlet is to support clients that do not support or accept cookies.

I will give a brief view of Session Tracking using cookies!
1. create a cookie- Cookie mycookie=new Cookie("name",value)
2. Cookies are sent as headers of the response to the client they are added with the addCookie method of the HttpServletResponse class
3.Retrieving cookie
4.Getting value of cookie
Hope u find this information useful
Have a Nice Day!
