I have a question about using a redirect for the Cj links.

CJ provides us with links, which look similar to "www.ncroape.com/b1435-243"

My question is can I use a redirect for that link, so I hide the original link?

So, instead of www.ncroape.com/b1435-243 , people would see "www.weight-loss.com/diet.php?=1"

Do you guys know if this is allowed, and whether it will affect the accuracy of the stats?
