Can you use WebSockets with HTTP?
WebSocket is distinct from HTTP. Both protocols are located at layer 7 in the OSI model and depend on TCP at layer 4. Although they are different, RFC 6455 states that WebSocket “is designed to work over HTTP ports 443 and 80 as well as to support HTTP proxies and intermediaries”, thus making it compatible with HTTP.
Does node js use WebSockets?

When should you not use a WebSocket?
