Hello,
is there affiliate software or service that allows affiliates to build dynamic destination URLs to merchant site?

So instead of:
aff-network/?vendor=123&aff=456
-> vendor/buy

Do this:
aff-network/?vendor=123&aff=456&redirect=/article5
-> vendor/article5

Idea is to give affiliates ability to send visitors to informative pages on merchant site and build buying decision gradually, instead of sending visitors straight to "buy" pages. Visitors should still get properly cookied.

Does it makes sense?
