"You need to be logged in" error after first course section

[icaptnbob]

The contents.url file contains all a course's pages, but the scrape_list_via_login.py populates urls for only the the first section of the course. After that, only the section headings are included.
This is because for some reason, the requests GET method doesn't work for the later urls, even if they are first in the file after the login POST method.
This seems to be something with the Code With Mosh site. I can't make out what is causing this.

This was noticed on the JavaScript Basics for Beginners course.
I haven't tested it on other courses yet.
