Web Filter - Logout authenticated user in browser

Question

Hello, 
 We have the Web Filtering option enabled on our SG105 UTM. We would like to know how a user can logout from a session using the browser. Is there a specific web address that he/she needs to visit to do so? 
 We have a single PC that is operated by more than one user which have different web filtering policies. Currently, we can't seem to find a way to logout a user who has already authenticated. The session continues even when we restart the browser. We are using Google Chrome. 
 
 Thanks,

Hi Rani, 
 I think it is not possible to force log out an authenticated user. I am working out of office and couldn't get hold on a test UTM to check if there is a way but, I found a feature request to logout users. Check,

 Try to disable the User and flush the authentication cache as a workaround if the feature is really not available in UTM. 
 Thanks

Sachin gave you the answer for your current setup. You could reduce the time that credentials are cached from 15 minutes, but that's probably not practical. 
 I have a suggestion for a possible workaround. I haven't tried it, but it should work... 
 Instead of using browser authentication, use the Sophos Authentication Agent. Set up a Web Filtering Profile for only the shared machine by putting only a Host object for the shared machine in 'Allowed Networks'. Select 'Default Authentication: Agent'. The shared machine will need to have the Agent installed separately under each User on the shared PC. When a user leaves the PC, the user must log off so that the next user browses with the correct credentials. Did that do what you want?
