Current CORS support only adds an Access-Control-Allow-Origin header to some requests. It also does not support the OPTIONS preflight sent by modern browsers. This commit adds support for OPTIONS preflight as well as more CORS headers.
The OPTIONS preflight is sent without any credentials attached to it so it mist take place before Authorization header processesing. Firefox 99 requires other access control headers like Access-Control-Allow-Headers be returned for a successful CORS interaction.
