I'm working through the first week 7 lecture (edx student). I've turned on the Cloud9 web server with:
apache50 start .
It gives me the URL at which my site is available. I can click on that link and it opens in another tab in the browser I'm using to access Cloud9. I can navigate to a web page I've created in that same browser. I've used chmod a+r to give read permissions to the web page (-rw-r--r--). I've tried it with the HTML file stored inside the pset6/public folder, and at the ~/workspace root.
Actual behavior: when I take the URL of my site or my page and put it in a different browser, it requests CS50 ID edX authentication. I can't view any of the pages I've created in the IDE on the web without signing into Cloud9.
Expected behavior: I can see the pages without sign-in, this is the behavior David demonstrates in the lecture.
