ASP Contents Collection

The Contents collection contains all the items appended to the application/session through a script command.

Tip: To remove items from the Contents collection, use the Remove and RemoveAll methods.

Parameter	Description

Examples for the Application Object

Example 1

Notice that both name and objtest would be appended to the Contents collection:

<%
Application("name")="W3Schools"
Set Application("objtest")=Server.CreateObject("ADODB.Connection")
%>

Example 2

To loop through the Contents collection:

<%
for each x in Application.Contents
Response.Write(x & "=" & Application.Contents(x) & " ")
next
%>

or:

<%
For i=1 to Application.Contents.Count
Response.Write(i & "=" & Application.Contents(i) & " ")
Next
%>

Example 3

<%
Application("date")="2001/05/05"
Application("author")="W3Schools"

for each x in Application.Contents
Response.Write(x & "=" & Application.Contents(x) & " ")
next
%>

Output:

date=2001/05/05
author=W3Schools
