logout

I can't seem to find a straightforward answer to this question. Is there a way in which I can force a logged in user to logout? My login system essentially just relies on a session containing the user's unique ID (which is stored in a mysql database). So essentially just... if (isset($_SESSION['user_id'])) { echo "You're logged in!"; } else { echo "You need to login!"; } But let's say I want to ban this user, well I can change their status to banned in my database but this won't do anything until the user logs out and attempts to log back in... So, how do I force this user to logout?

I have a website where I use Oauth to log users into Gmail, and then retrieve their contacts and other info. What do I need to do to ensure that when the user logs-off my website, he automatically logs out from Gmail too? As far as I know, there is no logout in OAuth. You simply stop sending tokens between your application and Gmail. Graeme This may be a shortcoming of the 3-legged OAuth flow. The user must sign into their account to provide consent, but once they provide the consent, the OAuth flow takes them away from Gmail. Since users are in a different mind-set when signing in to provide

I seem to have the same problem as in this question: Django logout problem Mine is a bit weirder, it works in google chrome.... but not in firefox... this is my logout function: (in views.py) def my_logout(request): logger.debug("Logout called by user") try: # Here I do some custom stuff, like logging this action in a database and so on # For this question it shouldn't matter... because in a try catch # so whatever goes wrong here, logging out should work anyway except Exception, e: logger.info("Logging logout action error: %s" % e) logout(request) return HttpResponseRedirect("/") in settings

On a website I have implemented the login using OpenID (based on StackOverflow). But I can't seem to logout. On my host I can logout but when the user tries to login again (especially with google) the authentication goes through without requiring the user to type in name and password. How can I indicate to the OpenID Provider that a user is no longer logged into the site? OpenID authenticates users to your site, when then starts a session on your site. You destroy or invalidate your site's session separately from the user's session with their OpenID provider. User visits joewidgets.com > User

My app uses Facebook SDK to post status updates. ALso there is a logout feature. I can login the first time the app is run. I can post status msg in facebook successfully. But once i logout , the subsequent runs and attempts to update status i encounter error from facebook saying "An error occured. Please try again later". I have noticed that the authorize method on subsequent attempts to login ( after the first logout) tries to use the same accessToken and accessExpires ( although i have set them to null and 0 respectively in the logout method) and in turn isSessionValid() method returns true
