CORS on Caddyserver version 1

To add the CORS authorization to the header using Caddy 1, simply add the following line inside your caddyfile:

cors

This will allow all resources to be accessed from every domain.

You can also be more specific, i.e. allow specific resources to specific domains:

cors /foo http://mysite.com http://anothertrustedsite.com

There are many more options you can use, here is a full example, as shown in the caddyserver docs:

cors / {
  origin            http://allowedSite.com
  origin            http://anotherSite.org https://anotherSite.org
  methods           POST,PUT
  allow_credentials false
  max_age           3600
  allowed_headers   X-Custom-Header,X-Foobar
  exposed_headers   X-Something-Special,SomethingElse
}
