<spy:logout /> seems to stop working if I log in from /webroot/index.spy and
tried to log out from /webroot/customer/index.spy.
Another thing I noticed is that if I login from /webroot/customer/index.spy,
I am required to login again when I go to /webroot/employee/index.spy.
Is the authentication information stored in a path specific cookie? How can
I get around this?
