Question

How can I log out user from facebook without authorizing him myself?

I have a public IPad which people come to, authorize in my application and do stuff.
One of the links leads to m.facebook.com/sharer.php?u=..
When the user presses it, he is redirected to facebook, which asks for his login/pass and makes the share.

Later then the user press Logout on my site
I need to log out him from facebook some way,
so the next user who will use the ipad and press share will post to his wall and not to the first user’s .

Same happens when i provide the iframe version of the Like button.
The first user logs in to facebook, makes the like, logs out of my web site,
and the next user see the like button pressed.

Thanks in advance 😉

Answer 1

I’ve just done some work with facebook recently on one of my projects and I used to visit a url to log them out it was something like

http://www.facebook.com/logout.php?redirect=your_url

It may not exactly be that as its off the top off my head but after visiting that the user got redirected to my site again logged out of facebook.

You may also have to provide a token.

Hope this helps!
