Currently when I use headless chrome (chrome –headless –dump-dom) to get the contents of sites that require login (but keep you logged in), I always get a redirect to the contents of the registration/login page, whereas with the GUI I get the expected content.

I’ve tried adding the –user-agent, –profile-directory, –enable-features=NetworkService, –user-data-dir and –login-user switches in various combinations, all to no avail. How can I get headless chrome to see what the GUI sees?
