This help does not mention about usage of this URL in multiple tabs in a browser. For example, calling one URL in the first tab, then the other URL in the second tab. It seems to open both tabs without problem, however once the user starts to use two tabs to operate within an application, it shows error. I am assuming this is caused by malfunctioning of session management.
Does anyone know whether this supports multiple tabs in a browser? If not, is there a way to prevent user to access using multiple tabs?
