Load a pages content from a random set

Hi,

I would like to have a page, say default.aspx, which when run would get pick its data at random from a predefined set.

I thought about using master pages, so that when the user visits the master page it randomly pulls its content from one of the content files. However, as I understand it, the user first visits the CONTENT page which then gets it layout from the MASTER page, which is no help to me.

Can someone suggest how I might achieve my goal?

Thank you very much fore your help,

Sam ...
