 * In-memory request logger. Use for very basic or testing purposes.
 *
 * CAUTION: it's not a good idea to use this when crawling large amounts of pages,
 * since memory usage keeps increasing, as well as the time consumed in this class.
 * Also this class does not work when working with multiple processes.
 *
 * You should configure one of the other loggers.
