Overview
Rack::CommonLogger forwards every request to the given app
,
and logs a line in the Apache common log
format to the logger
.
If logger
is nil, CommonLogger will fall back
rack.errors
, which is an instance of Rack::NullLogger.
logger
can be any class, including the standard library
Logger, and is expected to have a write
method, which accepts
the CommonLogger::FORMAT. According to the SPEC, the error stream must also
respond to puts
(which takes a single argument that responds
to to_s
), and flush
(which is called without
arguments in order to make the error appear for sure)
