Is it possible for an affiliate to track their returning customers?

[marttali]

"I read somewhere that out of ten sales nine are made by returning customers, and only one sale during the first visit to a site. The returning customer of course goes directly to the merchant site and if the merchant doesn't use cookies for tracking, the affiliate that referred the customer does no get a cent.
The figures above were given by a merchant that uses cookies, so they may be biased.

Has anyone here switched from a merchant that doesn't track returning traffic to one that does? How big was the difference." WAS POSTED BY ZeB sometime ago

MY QUESTION IS:
Let's say that i'm an affiliate of a bunch of sites. All of them give me a id. Now to prevent the problem that zeb talked about, is it possible to "plant" your own cookie or script into the visitors computer. I think it should work like that: Every time your customer types www.IDwebsite.com or IDwebsite.com into the browser it automatically adds your ID?
Well is it possible?
What kind of problems could occur?

i would remove the url drops first -> [webmasterworld.com...]

No is your answer a cookie is delivered and collect via the same site.

what you would need is some scumware sitting between desktop (IE) and the internet. this would check any url's requested and replace them with your own.

user type www.xxx123.com

ie output www.xxx123.com?id=12345 or www.myxxx1213.com
