Hi

I'm working in a security issue of the system that says that once you are logged into a session 
and you save this cookie. You can go to another navigator and use this cookie to be registered. 

I would like to chenge this cookie once user is logged into my system but I can't logout and 
login again because all my cookies are removed.

Is there a way to change to cookie or renew it?

Thanks a lot.
