    Session can be  maintain the each client only,but not more than one client.
    By using session you can pass the values from one page to anther page .

    ViewState allows the state of objects to be stored in a hidden field on the page. ViewState is transported to the client and back to the server, and is not stored on the server or any other external source. ViewState is maily used the retain the state of server-side objects between postabacks. while working with classic asp we used to have hidden variable to maintain the state of the object.

    Programmatically, session state is nothing more than memory in the shape of a dictionary or hash table, e.g. key-value pairs, which can be set and read for the duration of a user's session. For example, a user selects stocks to track and the Web application can store these values in the user's ASP session instance:
