Session Object

In an ASP application, a session has a more specific meaning. A session begins when a browser instance requests a page in your application, and ends when you abandon the session ia code, when the session times out, or - if the browser refuses the session cookie - immediately.
An ASP session is specific to a given cookie. That can be confusing because a cookie and a single browser are not the same thing. Bear in mind that the ASP engine identifies sessions by looking for the existence of an ASPSESSIONID cookie. You may have more than one browser window open and attached to the same session if both browsers have the same cookie.
ASP's reliance on cookies can cause problems because some people set their browsers to refuse cookies.
