Web App Version detection using fingerprinting
Good security practice tell us to only give our users the minimum privilege and least information necessary to do their jobs. Because of that, many people choose to hide the version of their systems and applications from outsiders.
It means we go around disabling banners, removing generators and headers from many of our servers, but sometimes it might not be enough for hide which version of a web application that you using.
Say this a few months ago, refound it today. Very cool.
