See your server's documentation for details pertaining to your server.The rest of this section describe the lowest-common-denominator functionality provided by Version 2.0 of the Servlet API. Every user of a site is associated with a object that servlets can use to store or retrieve information about that user.The level of support, however, depends on the server.
