I have actually set the following cookie for the following domain:
setcookie("thing", $data, time()+3600, "/", "example1.com", 1);
The cookie was set from this domain: example2.com
When I try to search for the cookie 'thing' I can't seem to find it. How is it possible to set a cookie on a domain, which will remain on another domain if I search for it?
UPDATE:
I basically want to pass a value from Domain A to Domain B. When a visitor arrives to Domain A he/she gets redirected AND pass a value to Domain B which I'd like to capture there.
How is it possible?
