How Google is managing authentication between multiple domains?
- by vaibhav
I think everyone here would be knowing that, if I am logged in any of the google's website(i.e www.orkut.com), I don't need to authenticate again for www.gmail.com.
How google is managing this. I think, it would be a cookie stored on user's browser. But, if it is a cookie, how different domains are able to read this cookie.
What do you say.
