Add support for custom domain #271

[sroertgen]

This PR adds support for custom domains as requested by @carlschuurbiers

@carlschuurbiers Would you mind testing this branch out to see if it fits your needs?

I added documentation about how to use the custom domain.

You just have to add custom_domain: "http://your-domain.org" to your config.yaml

Works for my case, only the custom logo is somehow broken, not sure what caused this, maybe it is not related, will need to check this.

Hat bei mir funktioniert, nur mein "custom logo" ist kaputt, bin mir nicht sicher was genau die Ursache ist, kann auch an was anderes gelegen haben, prüfe ich noch.

Attention: the custom domain must be a https:// because http:// doesn't work. For me not a problem because nowadays all sites are secure https:// or should be. Maybe consider adding an error message?

Achtung: der Custom Domain muss als https:// definiert sein, http:// funktioniert nicht. Sehe ich aber nicht als Problem da eigentlich alle Domains heutzutage https sein oder es sein sollten. Vielleicht Fehlermeldung einbauen?

Hey @carlschuurbiers ,

thanks for the review!

Regarding the protocol: If your vocabulary is hosted under http it should also work, but since this is not recommended and https is the standard nowadays, your protocol and server should reflect this.

I don't think the logo error is related to this and therefore I will now resolve conflicts and then merge.

If the error persists, open an issue. The logo should live in static/img/
