add header to site before requesting

[farbodpm]

I need to set some header because I have to set authentication token.

are you using selenium to access apis perhaps, if so you should look into reqwest? because it isn't meant to do that, most sites use cookies for auth, because that is the intended way to keep auth, since, not that I know of at least, browsers don't let you add headers to a request before sending
