When it encounters a difficulty, Polipo will print a friendly message.
The location where these messages go is controlled by the
configuration variables logFile and logSyslog.
If logSyslog is true, error messages go to the system log
facility given by logFacility. If logFile is set, it is
the name of a file where all output will accumulate. If logSyslog
is false and logFile is empty, messages go to the error
output of the process (normally the terminal).
The variable logFile defaults to empty if daemonise is
false, and to ‘/var/log/polipo’ otherwise.
The variable logSyslog defaults to false, and
logFacility defaults to ‘user’.
The amount of logging is controlled by the variable logLevel.
Please see the file ‘log.h’ in the Polipo sources for the
possible values of logLevel.
(Note that if you are using a shared cache, or logging to syslog,
an overly low logLevel could be a privacy violation.)
