What domains for duolingo.com are required?
I have a whitelist for my children to surf the internet. I also learned that some websites need additional domains to access to work. I looked into the source code of www.duolingo.com but can find any clear domains that could be required. www.duolingo.com (and *.dulingo.com) are not enough - the browser page stays white.
What other domains are required for duolingo.com to work?
These are the essential domains that I’ve whitelisted for Duolingo:
These domains are needed for the discussion forums in Duolingo:
This domain is needed for sound in Duolingo (when I’d used Duolingo without sound, I didn’t need to whitelist it):
This domain is needed to browse around the Incubator:
These domains aren’t essential for using Duolingo, though perhaps they provide benefits that I’m currently not enjoying (they might need to be whitelisted or not whitelisted as groups):
This domain has never been in my whitelist, so it’s not needed for Duolingo (at least when using Firefox):
EDIT: Updated for the new discussion forum domains.
