Tha Ad Rotator component enables you to show banner advertisements with different frequencies. This
component has one method, GetAdvertisement(), which displays a banner advertisement on a page.
Before you can use the Ad Rotator component, you need to create two special files: the Rotator Schedule
File and the Redirection File. The Rotator Schedule File lists information about all the banner
advertisements that should be shown. The Redirection File is used to record how frequently each
advertisement is clicked.
The three files below demonstrate how to use the Ad Rotator Component. Click View Demo to see a "live"
demonstration of this component.

<h3>This is the adredir.asp file</h3>
Normally, you would use this file to redirect a user
to the advertiser's home page. You can retrieve info
about which ad the user clicked by examining the following
query string variables:
<p><b>URL:</b> <%=Request( "url" )%>
<p><b>IMAGE:</b> <%=Request( "image" )%>
