application page caching

I'd like to cache a particular page at application level.

What is the the simplest way of doing this?

I tried caching on IIS 7, as per this article but it didn't seem to work:

Thanks

you can put this on top of the aspx page:

<%@ OutputCache Duration="60" VaryByParam="None"%>
