A group of ASP files that work together to perform some purpose

is called an application.

The Application object is used to tie these files together.


Application Object

An application on the Web may consists of several ASP files that work together to perform some purpose.

The Application object is used to tie these files together.

The Application object is used to store and access variables from any page, just like the Session object. The difference

is that ALL users share ONE Application object (with Sessions there is ONE Session object for EACH user).

The Application object holds information that will be used by many pages in the application (like database connection information).

The information can be accessed from any page. The information can also be changed in one place, and the changes will automatically be reflected

on all pages.

The Application object's collections, methods, and events are described

below:

Collections

Contents

Contains all the items appended to the application

through a script command

StaticObjects

Methods

Method Description

Contents.Remove

Contents.RemoveAll()

Lock
