* To enable this, add the following lines into any config file:
|

*
|

* <Location /server-status>
|

* SetHandler server-status
|

* </Location>
|

*
|

* http://your_server_name/server-status
|
||||
*
|
||||
* /server-status - Returns page using tables
|

* /server-status?notable - Returns page for browsers without table support
|
||||
* /server-status?refresh - Returns page with 1 second refresh
|
||||
* /server-status?refresh=6 - Returns page with refresh every 6 seconds
|
||||
* /server-status?auto - Returns page with data for automatic parsing
