Reading Cookie from a different domain?

[kam bansal]

Hi all,

Can javascript read a cookie from a different domain? Meaning, if my
html page is running on "www.mydomain.c om" and I goto another domain
"www.another.co m" to do some work, and then I come back, can I see the
cookie that "www.another.co m" created from my domain???

Any thoughts?

No, that would be a big security breach.

The only thing you can do to transmit information between
www.another.com and www.mydomain.com is call the URL with parameters,
for example:

www.mydomain.com?param1=value1&param2=value2

I could swear that there is a way to do this. You can share cookies with
your other sites in some way (seems to me it involved using IP addresses
instead of domains.) Not really recommended though.

That depends on security settings.
If you have "disallow third party cookies", then it won't work. Then
"www.another.co m" cannot set cookies for other domains than itself.

If not, you can set the cookies with a domain of "mydomain.c om".
IIRC:
document.cookie = "dims=data;doma in=www.mydomain .com;path=/;expires=..."
