For example I have seen this behavior in FF. I go to ESPNcricinfo and click on an article and read it and go back, the page rendered does not have the score refreshed. This same behavior is exhibited when you press CTRL+SHIFT+T to reopen closed tabs. The rendered page is loaded as well as the history of the tab. Do you see this behavior with Flask-login as well ? And what browser are you using to test ? I have seen some sites try to disable the back-button but that might not be an elegant way to do this. Another approach could be see if you can play with the HTTP Cache-control headers to see if they make a difference. -- Vinayak _______________________________________________ BangPypers mailing list BangPypers@python.org https://mail.python.org/mailman/listinfo/bangpypers
