As far as i know tomcat sets the path variable in your cookie to /
instead  of /webapp if emptySessionPath is true. That means the cookie
information is send to the app for each request http://localhost/.....
If this is not set, the cookie information is only sent if your request
is http://localhost/webapp i.e. your cookie path is equal to /webapp.

BTW did you check the path variable in your browsers cookie? What is
it's value? I could imagine that it is /webapp but your request is
something like http://www.example.com/lenya/..... due to your proxy
settings. That means the path in your cookie (/webapp) does not match
/lenya in the request and hence the cookie information is not sent to
the app :-( and a new session will be created.
IMHO there are at least two possibilities to solve that problem:
1. use emptySessionPath in your tomcat setup or
2. use proxy setting which have the real application context in it in
your case http://www.example.com/webapp/customer/authoring instead of
http://www.example.com/lenya/customer/authoring
3. I did not know whether Michis solution works with your setup.
