Your web application can contain a page that lets registered users log in to the site.
A login page is made up of the following building blocks:
A database table of registered users
An HTML form to let users enter a user name and password
A Log In User server behavior to make sure the entered user name and password are valid
A session variable consisting of the user name is created for the user when the user logs in successfully.
The method you use is identical for ColdFusion, ASP, JSP, and PHP pages. Dreamweaver does not have authentication server behaviors for ASP.NET pages.
