Setting a cookie for a different domain

I'm trying to propagate a cookie for a different domain.

Let's say that my script that's setting the cookie is at the following address:

and I'm setting the cookie for www.example.com
Whatever I try, there's no way to see it from the example.com domain.

I'm using

setcookie("mycookie", "bla", 0, "/", "www.example.com");

What's wrong with it? Is there any limitation to cookies from different domains?

Yeah, I believe you cannot set cookies in the name of other domains

So what's the point in having the chance to set the domain too?

You can set from within subdomains. For example, if your script is in www1.domain.com, you can set the cookie to be available in domain.com.
