thanks but I'm not sure I understand your GET method. I can't install a php script on the target domain (siteb), i can only add something to the thankyou page.

this is what im trying to achive:

Commission Monster uses a cookie based method to track sales, leads and clicks through it's network. Cookies are the most popular form of affiliate tracking as they provide a great solution to the stateless nature of the http protocol. In short when an internet user clicks your link on an affiliate's website the user will be transported to our server briefly where a cookie is set in their browser before our server redirects them to your website. You need to place our tracking pixel on your thank you page. This will be the page where the desired action has been completed like "your order number is #" or "thank you for completing our survey". If the internet user buys something from your website or completes a lead action when shown this page the <img> tag will execute a script that checks the internet users computer for our cookie. If the cookie indicates that the user was sent from an affiliate's website our system will credit the affiliate and debit your account for the respective amount due.
