Rudder

When I use Rudder I often open multiple tabs as is usual with a browser.

However this poses multiples problems :

• If I log out from one tab I get logged out from other tabs (a good thing)
• I can log in back into one tab, but them it becomes impossible to recover the other tabs:
  • if I reload them they stay on the login page
  • if I try to re log in it disconnects my from the first one
  • the back button is not working to come back to the previous page

If it is not technically possible to log in again, it should at least be possible to have a link 'i logged in from another tab please please bring me back where I was'

• If I have one tab open and logged in and another tab where i'm not, i get disconnected every 20s, which is very annoying
• I have to guess there is another tab open, find it, and close it to end this behavior

Another problem is that the port is ignored in the session cookie, which means that if i test 2 rudder on a localhost url, i cannot compare them, i have to test one, wait, then test the other.
