Ok, but a daft question, shouldn't the backend itself make CORS headers configurable? @utxo the webmaster 🧑‍💻

In my repo, I don't even want to install Nginx proxies, because every server operator should be able to configure and start those proxies themselves.

Of course it works with the header-configs from @Anthony Accioly, but it doesn't look great to open it at location level.

But I can see from the comments that we are apparently working on Haven. Super cool. 

 This one is on me Ben. Don't worry, Haven will have proper CORS support OOB soon. I just need some patience as I'm travelling and working on a gazillion other things at the moment and I want to get this right.
