How to setup split test?

Question

I want to create a way to test different layouts on a page to see which get more conversions.

For example. If I have 2 versions of a page and I send 50% to page A and 50% to page B and see which one converts more sales.

So I am thinking maybe use .htaccess to rewrite half to page A and the other half to page B.

But how can I do that with .htaccess is there a way? do I need to use PHP instead to do this?

Also if there is a better way to do this, or any cautions I should be aware of, please let me know.

Lots of ways to deal with it on your own code. If however you're already using Google Analytics and don't care to use javascript for the test, spare yourself a lot of trouble and look at http://www.google.com/websiteoptimizer/index.html

Update (Reconfine): Google website optimizer no longer exists, this has been replaced with "Google Analytics content experiments" https://developers.google.com/analytics/devguides/platform/experiments-overview
