Scrapy

Yes, you can use BeautifulSoup for parsing HTML responses in Scrapy callbacks. You need to feed the response's body into a BeautifulSoup object to extract data.

Yes, Scrapy supports HTTP proxies through the HTTP Proxy downloader middleware, which has been available since Scrapy 0.8.

You can use FormRequest.from_response() to simulate a user login in your spider.

If you have a spider with a long list of allowed domains, consider replacing the default OffsiteMiddleware with a custom downloader middleware that requires less memory. You can also use pyre2 instead of Python's re to compile your URL-filtering regular expression.

Yes, you can use the runspider command to run a spider without creating a project. For example, you can run a spider written in a my_spider.py file with the command: scrapy runspider my_spider.py.

To avoid getting banned, you can follow the guidelines provided in the Avoiding getting banned section of the Scrapy documentation.

Yes, Scrapy automatically receives and keeps track of cookies sent by servers, and sends them back on subsequent requests, similar to how a regular web browser operates.

You can enable the COOKIES_DEBUG setting to see the cookies being sent and received from Scrapy.
