mock-api should show clear feedback for valid session

[oscgonfer]

Hi,

So this issue is to just have in the list to implement a visual and clear feedback for the user to know whether the actual session is valid or not for the configuration webserver (maybe via cookie?).

It has been reported many times, specially in more modern web browsers that keep cached pages, and it's an issue that could reduce the support questions...

Open for discussion below in the issue.
