This answer taught me that you can set headers for an entire session:
s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})
# Both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})
Bonus: Sessions also handle cookies

Authorization headers set with headers= will be overridden if credentials are specified in .netrc, which in turn will be overridden by the auth= parameter. Requests will search for the netrc file at ~/.netrc, ~/_netrc, or at the path specified by the NETRC environment variable.

How do I rotate headers to avoid detection?

Why do my headers work in testing but fail in production?
This is usually because you're sending too many requests. In testing, your low number of requests doesn't trigger extra anti-bot checks. In production, more requests trigger TLS fingerprinting. Even with perfect headers, a different TLS fingerprint will get you blocked. ScrapFly solves this by using real browser TLS profiles.

When should I use browser automation instead of requests?
Use browser automation tools like Playwright or Selenium when you need to load JavaScript, handle clicks, or when you're blocked by TLS fingerprinting. While these tools solve the TLS problem, they are slower and use more computer resources. ScrapFly offers both simple requests and full browser automation.

We can also check if the response obtained is a well-formed HTTP redirect (or not) that could have been processed automatically using the req.is_redirect property. This will return True or False based on the response obtained. You can also get the time elapsed between sending the request and getting back a response using another property.

December 16, 2021 -
Hey everyone. I am trying to create a web scraping program. However, I am facing some difficulties with getting valid request headers. These headers are initialized randomly through Javascript scripts when the website is loaded. I am able to get these scripts, but I want to be able to run them in my script just like a browser would. What can I use to do this? I was looking at requests-html. What do you guys think of this? Is there something better than this? Below is a piece of code I was trying in order to run the script, but it didn't work. My method is probably wrong, but I want to know how to run a script that is returned when I do a GET request
from requests_html import HTMLSession
sess = HTMLSession()
r = sess.get('url_of_javascript_function')
r.html.render()
