https://cloud.sagemath.com/project_id/port/<port number>/You have to configure your web service so that the base url is /project_id/port/<port number>/ or you may find that things don't work. This may be either easy or impossibly hard. Websockets should be proxied fine. Note -- the project_id can be read from ~/.sagemathcloud/info.json.
Only project collaborators will be able to access your web service, so you do not have to worry about authentication or running web services that provide local shell access (e.g., a sage cell server). All access to the web service is encrypted. (If you are lazy and allow your service to listen on localhost, then you should require authentication.)
This feature is not designed for making a web service that is accessible to the general public, since it is limited to project collaborators. It's designed for use by a small group of trusted users.
