Question

Regarding this specification: http://www.w3.org/TR/eventsource/

How does one close the opened connection on the server? Client-side wise it is easy, just call close(), but what should I do on the server? Just kill it?

Answer 1

node.js:

http.createServer(function (req, res) {

    //...

    // client closes connection
    res.socket.on('close', function () {
      res.end();
      //...
    });

});

see example for implementation of SSE server in node.js:
