What I did was to use a "one shot cookie", a request was only ever made 
by user interaction.
The server basically get a token cookie and a id cookie. the server the 
responds and set the cookies for deletion. There is only ever one token 
and one id cookie sent, re-using the cookie names are not an issue.

Now if each tab automatically makes requests then that is a different 
issue and in that case using POST instead of GET is advised, in that 
case you only ever have to send cookies from the server and not to the 
server.
