ASP and ColdFusion application variables
In ASP and ColdFusion, you can use application variables to store and display information that is maintained for the lifetime of the application and persists from user to user. The applications lifetime lasts from the time the first user requests a page in the application to the time the web server is stopped. (An application is defined as all the files in a virtual directory and its subdirectories.)
Because application variables last for the lifetime of the application, and persist from user to user, theyre ideal for storing information that must exist for all users, such as the current time and date. The value of the application variable is defined in the applications code.
