+/* Status Module. Display lots of internal data about how Apache is

+ *
+ * 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)
