If the application is not otherwise interested in -// messages from the peer, then the application should start a goroutine to read -// and discard messages from the peer. A simple example is: -// -// func readLoop(c *websocket.Conn) { -// for { -// if _, _, err := c.NextReader(); err != nil { -// c.Close() -// break -// } -// } -// } -// -// Origin Considerations -// -// Web browsers allow Javascript applications to open a WebSocket connection to -// any host. It's up to the server to enforce an origin policy using the Origin -// request header sent by the browser. -// -// The Upgrader calls the function specified in the CheckOrigin field to check -// the origin. If the CheckOrigin function returns false, then the Upgrade -// method fails the WebSocket handshake with HTTP status 403. -// -// If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail -// the handshake if the Origin request header is present and not equal to the -// Host request header. -// -// An application can allow connections from any origin by specifying a -// function that always returns true: -// -// var upgrader = websocket.Upgrader{ -// CheckOrigin: func(r *http.Request) bool { return true }, -// } -// -// The deprecated Upgrade function does not enforce an origin policy.
