We have fixed an intermittent bug when admins access their site by typing URL into Chrome address bar
Chrome has a feature whereby it tries to speed up the user experience by 'guessing' which website you want to visit when you are typing the URL into the address bar. It has a list of auto complete options and starts loading the website before you have pressed enter. When you do press enter it resends another request. This used to cause occassional issues in pagebloom when your previous session had already timed out - it could occasionally result in a 'page not found' error. The page could be reached by hitting enter again or doing a refresh but that is no longer necessary as we now accomodate the Chrome browser's "double pump" requests.
