CLogFilter is meant to be used by a log route to preprocess the logged messages before they are handled by the route. The default implementation of CLogFilter prepends additional context information to the logged messages. In particular, by setting logVars, predefined PHP variables such as $_SERVER, $_POST, etc. can be saved as a log message, which may help identify/debug issues encountered.
