CORS

Added an option to skip returning the Access-Control-Allow-Origin response header when requests don’t have the Origin header.

Fixed an issue where the Access-Control-Allow-Origin header was not sent when conf.origins has multiple entries but includes *.

Support the Access-Control-Request-Private-Network header in crossing-origin pre-light requests
