There is some desire to have a web dashboard for the gateway. So that we dont have to proxy all requests through the webserver and expose credentials over the wire, the better approach would be to enable CORS headers to allow browser requests directly to the s3/admin service. The default for these headers is off, so that they are only enabled for instances that specfically want to support this workload.
