A page can be directly accessed by typing its full URL into the browser's navigation bar, e.g. http://host:port/Curam/en_US/SomePage.do. In this scenario the session and its associated tabs will first be restored, then a request will be sent for the specified page. The page will then be loaded in it's associated section and tab. However, if this page is not associated with a tab, it will be loaded in the currently selected tab. In the case of a new session, this will be the "Home" tab.
Tabs changed in this manner can be returned to their default state by closing and reopening the tab where possible. For the "Home" tab; logging out and back into the application will restore the "Home" tab to the user's default home page. See Tab Restoration for more information on tab restoration and session management.
