Tracking Affiliate Cookies - Need Help Please :)

You'll need to use the same domain as your free report so you can read the cookies. Then you can send them on somewhere else.

The easiest way is if they're on the same domain, but it is possible to do.

The following is pretty technical, so point your developer at it:

Probably the best way is to have both of these domains running on the same server, with access to a shared database. The first domain, domain1 will set the cookie normally (plus add the user's IP and cookie to a row in the database). It will also have a server side script that, when hit, will again add a row to a database with the user's IP and cookie (only if they have a cookie though - if no cookie, no need to add the row) and it'll return a 1x1 pixel image. On domain2, you need to have an image tag pointing to a page that runs that server side script on domain1, and on every page on domain2 (server-side) you need to check to see if the user's IP is in that database and if so, set the cookie.

The end result is that you set a cookie on domain1, then the user goes to a page on domain2 and they have their cookie set in the context of domain2. The worst case scenario is when the user visits domain1 and then their IP changes - in that case though, it only takes two page hits on domain2 to get it set again (first page hit they also hit the script on domain1 and now the server knows their IP, second page hit will set the cookie). Even this could be fixed with some ajax to set the cookie though.

I need a help from you all. I have a site and i want to track the number of visitors whose machine the cookies are being installed on. Then what should I do and how can I track this ? Need Your suggestions...

Can't you send them to the iDevaffiliate site (which sets the cookie) first and then automatically/instantly redirect to the free report site. When launching remove the redirection and put the sales offer there instead
