Provide a way to disable hostname canonicalization #21

Closed mithrandi closed 8 years ago

mithrandi commented 9 years ago

The ability to have multiple canonical hostnames was planned previously, but for sites that don't need to use the websharing-by-username-in-hostname feature, there's no real need to care about canonicalization; resources can just be served from whatever hostname the page was requested from. All that is required is a way to turn off the canonicalization.

Very rough sketch of how to implement this, copied from an ad-hoc patch we have deployed already:

I think the change to publicweb is not actually needed given the change to SiteConfiguration but this needs to be tested.
