rails rack application, per rails documentation,

rails.application primary rack application object of rails application. rack compliant web server should using rails.application object serve rails application.

since rack wraps http requests , responses, 1 may not able build pure tcp ip socket based interaction rails server.

however, may want have @ action cable, new addition rails 5 - integrates websockets rails application. per wikipedia,

the websocket protocol independent tcp-based protocol. relationship http handshake interpreted http servers upgrade request.

how extract action cable work non browser clients may tricky given rails web application framework.
