I would like to run a simple A/B split test, but only want to show Version B to a particular IP address and have everyone else see the original page (Version A). Can this be done? If so, how exactly? I dont quite understand all of the code for this script.

I have a small problem, though, and was wondering if you might be able to help. I have a scenario where the code executes properly, but only when loaded locally (i.e. I open the file in my explorer). When the page is opened on my local testing server or uploaded to the domain the code does not work.

I can see that the application is setting the cookies correctly in the later scenario – where the code does not work.

It sets two values for __utmx

1. Content: ID:3:0-1
Domain: domain.com
Expires: …2010…

2. Content: ID:3:0-0
Host:domain.com
Expires …2008…

Like I said, when this is executed locally, the code works as it supposed to: the first variation takes precedence. So 0-0, 1-1 and 2-2 are the only possible values seen in the cookie.

Do you have any advice on this issue?

Thanks in advance!

Though i think this can be very useful for specific situations, IMO, A/B testing can generally resolve the problem for testing specific navigation schemes. You just have to create multiple copies of your page, with the specific combinations you want to test.

That being said, it is not always that easy and your hack can come in handy!
