thanks guys .

however, I am afraid sessions is not what I am looking for.
I mean, keeping the same version during the visit of the same user is
not my primary goal, the split run testing is needed to know which
different creative/ layout option ( ie some copy in the text , the
position of a form etc. ) is more efficient.

So the test is usually performed on single pages, often homepages or,
better, landing pages.

What is really important is that if for instance I have to test 3
different version of something, each option must have the same number
of impressions in order to have reliable stats to anlayze ( so 33,3%
of visitors must have seen one of the 3 different pages).

I realized that I should have a look at banner rotation management
scripts without using any random function because the core of my script
must be an equal number of views for each version.

I had no time to search properlly the web for those scripts yet but the
only one I have saw used a database table to know each time which
version of the banner has to be included in the page following an array
order

Anyway , any suggestion is always welcome
