ASP and Web Session Management

Introduction
One of the challenges faced by Web developers is how to create a coherent application out of a series of independent HTML pages. This problem is a particular concern in Web development because HTTP is a stateless protocol. Each browser request to a Web server is independent, and the server retains no memory of a browser's past requests. The HTTP 1.0 protocol did not provide a mechanism to maintain state information between requests from a browser.
To overcome this limitation, application developers require a technique to provide consistent user sessions on the Web. Active Server Pages (ASP) provides powerful and flexible Web session management that requires no special programming. The Session object, one of the intrinsic objects supported by ASP, provides a developer with a complete Web session management solution.
The Session object supports a dynamic associative array that a script can use to store information. Scalar variables and object references can be stored in the session object. A script simply assigns a value to a named entry in the array ......
