There are two types of configuration settings within the
Zeus Web Server; those that control individual virtual
servers (per-Virtual Server configuration), and those that
affect all Virtual Servers for a given Zeus instance (global
configuration).
Per-Virtual Server configurations are stored in individual
Virtual Server configuration files in
$ZEUSHOME/webadmin/conf/sites directory.
The following is a comprehensive list of all global and
per-Virtual Server configuration parameters. For more details
on per-Virtual Server configurations, please refer to the
Zeus Web Server product documentation. For more details on
configuration and tuning, see the Support Web site.
