I have seen at www.affiliateseeking.com, the affiliate links are cloaked in php with id's. And on clicking the links, it goes to the affiliate url. for example:http://www.affiliateseeking.com/affclick.php?linkid=xxxx what i understand is that the affiliate links are provided with an unique id and stored in mysql database. then on calling affclick.php?linkid=xxxx it is being redirected to affiliate pages. Well, what i need is how this is done? is there any php scripts doing the above action help needed urgently for construction of website
