While phhttpd is running it listens to a 'control' socket for messages from the
administrator. The currently provided phhttpd_ctl program allows
the administrator to minimally interact with phhttpd. This provides both control
and status reporting.
phhttpd_ctl always wants a --control argument
that specifies the control socket of the running phhttpd daemon. This should match
the <control> tag specified in the config file.
phhttpd can be told to rotate its logs so that existing logs may be processed.
The --rotate argument to phhttpd_ctl tells phhttpd
to rename the existing files to a unique name, open new files with the previously used names,
then close the renamed logs and start using the newly created files. phhttpd_ctl
will output the names of the newly created files which will be safe to use once the command
exits.
The --reopen argument to phhttpd_ctl tells phhttpd
to close the existing file logs and reopen the files with the filenames that were configured.
This implies that an external entity has moved the files to new names and wants phhttpd
to stop using them.
