| /* Status Module. Display lots of internal data about how Apache is |
| * performing and the state of all children processes. |
| * |
| * To enable this, add the following lines into any config file: |
| * |
| * <Location /server-status> |
| * SetHandler server-status |
| * </Location> |
| * |
| * You may want to protect this location by password or domain so no one |
| * else can look at it. Then you can access the statistics with a URL like: |
| * |
| * 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 |

| * Mark Cox, mark@ukweb.com, November 1995 |
| * |
| * 12.11.95 Initial version for www.telescope.org |
| * 13.3.96 Updated to remove rprintf's [Mark] |
| * 18.3.96 Added CPU usage, process information, and tidied [Ben Laurie] |
| * 18.3.96 Make extra Scoreboard variables #definable |
| * 25.3.96 Make short report have full precision [Ben Laurie suggested] |
| * 25.3.96 Show uptime better [Mark/Ben Laurie] |
| * 29.3.96 Better HTML and explanation [Mark/Rob Hartill suggested] |
| * 09.4.96 Added message for non-STATUS compiled version |
| * 18.4.96 Added per child and per slot counters [Jim Jagielski] |
| * 01.5.96 Table format, cleanup, even more spiffy data [Chuck Murcko/Jim J.] |
| * 18.5.96 Adapted to use new rprintf() routine, incidentally fixing a missing |
| * piece in short reports [Ben Laurie] |
| * 21.5.96 Additional Status codes (DNS and LOGGING only enabled if |
| * extended STATUS is enabled) [George Burgyan/Jim J.] |
| * 10.8.98 Allow for extended status info at runtime (no more STATUS) |
| * [Jim J.] |
