I have web page x.com. I am directing traffic to my web page through various sources.
I want my web page to drop a cookie only to one of those sources, not to all. So if you come on [login to view URL] through Facebook, you will get the cookie, but if you come through any other source, you will not get or see the cookie.
I need this to be done asap. Please place your bid or describe how this would be done. l
