Application Object

An application on the Web is a group of asp files. These files work together to perform some purpose. The Application object is used to tie these files together.
The Application object is used to store variables and access variables from any page. All users share ONE Application object.
The Application object should hold information that will be used by many pages in the application (like database connection information). This means that you can access the information from any page. It also means that you can change the information in one place and the new information will automatically be reflected on all pages.
