Hi

We are conducting a test with our website.
We are going to redirect every 1 in 10 visitors to a new default homepage to
determine the effectiveness of this page.

I'm looking for ideas on how to do this.

1 thought i've already had:

   Everytime a visitor comes to the site, i can hold an application
variable with a number in it, and increment it by 1.
   When that gets to 10, i can send that user to the test default page, and
reset the app variable back to one.

Any other ideas, or better methods.
Or even problems with this potential method.

Thanks for any help on this
