You can use session variables to store and display information maintained for the duration of a user’s visit (or session). The server creates a different session object for each user and maintains it for a set period of time or until the object is explicitly terminated.
Before defining session variables for a page, you must create them in the source code. After you create a session variable in the web application’s source code, you can use Dreamweaver to retrieve its value and use it in a web page.
