 * String, the path and file name where the logs will be stored.
 
+In case you want to hide the header values from the requests on the logs use the option `log_headers`. Possible values:
+* :all, (default), will log all header values.
+* :none, won't log any value of the headers.
+* :partial, will log only the last 10 characters of the header values.
