-; By default the status page output is formatted as text/plain. Passing either
-; 'html', 'xml' or 'json' in the query string will return the corresponding

-;   http://www.foo.bar/status?json&full

-;   request URI          - the request URI with the query string;
-;   content length       - the content length of the request (only with POST);
-;   user                 - the user (PHP_AUTH_USER) (or '-' if not set);
-;   script               - the main script called (or '-' if not set);
-;   last request cpu     - the %cpu the last request consumed
-;                          it's always 0 if the process is not in Idle state
-;                          because CPU calculation is done when the request
-;                          processing has terminated;
-;   last request memory  - the max amount of memory the last request consumed
-;                          it's always 0 if the process is not in Idle state
-;                          because memory calculation is done when the request
-;                          processing has terminated;
-; If the process is in Idle state, then informations are related to the
-; last request the process has served. Otherwise informations are related to
-; the current request being served.

-
-; Clear environment in FPM workers
-; Prevents arbitrary environment variables from reaching FPM worker processes
-; by clearing the environment in workers before env vars specified in this
