Socket.io is constantly conducting a survey ... if so?

Question

I have a node server and a webpage connected via socket.io. I noticed in the browser console that it displays

XHR finished loading: GET "http://my_url/socket.io/?EIO=3&transport=polling&t=1418944327412-412&sid=vqLTUtW3QhNLwQG8AAAA".

and

XHR finished loading: POST "http://my_url/socket.io/?EIO=3&transport=polling&t=1418944385398-415&sid=vqLTUtW3QhNLwQG8AAAA".

every few seconds. If so, or I am missing the settings. I really only want to send data back and forth explicitly through the socket. Maybe I missed something in the setup.

Client side mainly

var socket = io("http://my_url");

with ordinary event listeners. Server side

var io = require('socket.io')(server);

I tried to host this server side

io.set('transports', ['websocket']);

but that seemed to kill him.
