JServ 1.1 create one coookie name / zone (see what's happening on the
FAQ on java.apache.org when displaying the cookies :
JServSessionIdjikes=dyguidu
which was a way to :
- allow load-balancing of zones on different JServs (in the same virtual
host)
- create context sessions for zones, useful for ISP by exmples.

are there any people around (in jserv area) that don't read jakarta
