When I enter gmail and open orkut in a new tab or in a new window, then I automatically join orkut without entering a username and password. How does this functionality work ...? And when I exit any site, I also sign ou from another site .. is this done with a handeling or cookie session ..? what is the mechanism of this functionality .. ??
Both use the central Google login system, which will store the cookie. When you exit one, it deletes the cookie and takes you out of both.
