reference and then writes a message:

Sub Page_Load( )

Application.Contents.RemoveAll( )

Notes

This property is provided for backward compatibility with classic ASP. Properties

such as the Item property and methods such as Remove and RemoveAll were

accessed via the Contents property in classic ASP. In new ASP.NET development,

you should access these members directly. For example, instead of calling the

RemoveAll method through the Contents property, you can call RemoveAll

method directly:

Application.RemoveAll( )

associated with all values stored in the Application collection.

KeysCollection

A variable of type NameObjectCollectionBase.KeysCollection that will
