I'm looking for the easiest and best way to have a different index.html file to load (randomly) each time someone visits my domain. I made 4 designs that I want to randomly load. I thought I could use the Cpanel random HTML feature in the scripts library, but I'm not entirely sure how that'd work. Any ideas on this?

I know of a way to do this in javascript, but is there any non-javascript way since some people disable javascript?
