Description Mauro Matteo Cascella 2022-03-02 14:03:39 UTC 
A flaw was found in python-scrapy. If you manually define cookies on a Request object, and that Request object gets a redirect response, the new Request object scheduled to follow the redirect keeps those user-defined cookies, regardless of the target domain.
