Application Object
An application on the Web may be a group of ASP files. The ASP files work together to perform some purpose.
The Application object in ASP 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, while with Sessions there
is one Session object for EACH user.
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 changes will automatically be reflected on
all pages.
The Application object's collections, methods, and events are described
below:
Collections
| Collection |

| Contents |

through a script command |
