I am getting authentication page twice on opening any browser for first time. I am using tomcat authentication. On opening fresh browser (not new tab) when i try my url, Authentication page gets loaded(its behavior). After entering credentials on giving login button, Authentication page shows again. but in backend it gets authenticated correctly as expected. It happens only when opening browser freshly and tried url. This not happen when i am clearing entire browser data (cookies, site-information, etc) and tried url. but when i am giving url with appending some path like (site-name:port-number/home.do). It doesnt show double authentication page even when browser opened freshly.
