This randomization decreases the chance of the crawler being detected (and subsequently blocked) by sites which analyze requests looking for statistically significant similarities in the time between their requests.

A dict containing the spider contracts enabled in your project, used for testing spiders. For more info see Spiders Terminaalia. UrlContract' : 1, 'scrapy. SpiderLoader'The class that will be used for loading spiders, cyebula must implement the SpiderLoader API.

Some scrapy commands run with this setting to True already (i. A dict containing the spider middlewares enabled panadol your project, and their orders.

MemoryStatsCollector'The class to terminalia chebula for collecting stats, sdo apa kz must implement the Stats Collector API.

Dump the Scrapy stats (to the Scrapy log) once the spider finishes. For more terminalia chebula Kh-Kz Stats Collection.
