Where can i find a live server that returns a multipart response

I am experimenting on HTTP(S) response.

My experiments also includes the multipart response.

So i am looking for a live server that returns a multipart response.

Can anyone suggest some public links for the same.

I have googled and i found this https://blog.miguelgrinberg.com/post/video-streaming-with-flask

But the example does is not detected though the response handler for request package. (https://npmjs.com/package/request)

console.log(toSend) // prints
request(toSend,function(){
  console.log(arguments) // does not prints
})

Any help to find detectable multipart response in nodejs.
