[azipa] Linux SA Position (fwd) (Application Server)

On the job posting by der.hans, (I don't qualify, just have a question) it
says

^^^^^^^^^^^^^^^^^^^^^^^^^
.....Pix Firewall, Extreme Switch,
DNS, Samba (Linux and
Windows NT), Mail Server,
Apache Webserver,
Application Server
and Sybase Database.......
^^^^^^^^^^^^^^^^^^^^^^^^^

When they say "Application Server" what would that be?


Thanks,
