 DEFAULT_ERRBACK_NAME
 ~~~~~~~~~~~~~~~~~~~~
 
-The name of the default errback method to call on the spider in case of an exception. The default errback method is ``parse`` to maintain backwards compatibility but it is not standard to scrapy and may interfere with the use of middlewares which implement the ``process_spider_exception`` method. Use a setting of ``None`` if you don't want to use the default scrapy exception handling.
