I am trying to optimize my website and the first thing on the list to decrease page speed is to leverage browser caching. The Microsoft msdn site says:

"To implement page output caching, simply add an OutputCache directive to the page:
<%@ OutputCache Duration="60" VaryByParam="*" %>"

How can this be done?

I would avoid this, IMHO you'll cause more harm than good. The easiest and most effective way is to cache your images and theme folders in IIS. https://mohamedradwan.wordpress.com/201 ... -in-iis-7/

Thanks for the info, but I don't have access to IIS on this server.

By the way, what is IMHO?
