I have made a openid login system using google, yahoo which is working fine, problem is when user logout from my site it doses not logout from google, yahoo. how to make a global logout which logout user from my site and also from google, yahoo.
a simple session_destroy();
only logout from my site.
in order to logout from google and yahoo i need to trigger these url in background.
https://mail.google.com/?logout
http://login.yahoo.com/?logout=1
i can use some form submission method to take the user to these url but it will then show the respective google, yahoo logout page, i want to log them out and show them my site logout page.
Please see and suggest any way to do it.
Thanks.
