example, the fetch command will use spider-overridden behaviours (such as custom USER_AGENT per-spider setting) if the url being fetched is associated with some specific spider. This is intentional, as the fetch edit • Requires project: yes Edit the given spider using the editor defined in the EDITOR setting. This command is provided only as a convenient shortcut for the most common case, the developer is project: no Get the value of a Scrapy setting. If used inside a project it’ll show the project setting value, otherwise it’ll show the default Scrapy value for that setting. Example usage: $ scrapy settings

gives you control over the politeness of the crawl through a few settings. You can do things like setting a download delay between each request, limiting amount of concurrent requests per domain or per IP problem of hitting servers too much because of a programming mistake. This can be configured by the setting DUPEFILTER_CLASS. Hopefully by now you have a good understanding of how to use the mechanism of following given spider using the editor defined in the EDITOR environment variable or (if unset) the EDITOR setting.
