server-sent-events

How can I change the source set in declaration of EventSource ? I have tried something like this: var source = new EventSource("/blahblah.php?path=" + (window.location.pathname)); // Few lines later... source.url = "/blahblah.php?path=" + url; But, source.url stays the same... Is this even possible? Or maybe there are alternative ways to do that? No, it is not possible. A new URL passed to EventSource() creates a new EventSource object. guest271314 suggested me much solutions to this, but for me it would be much better, faster and less complicated to stay with sse. I changed the source by

Is there any way of viewing/debugging Server-Sent Events in Chrome (or perhaps Firefox)? I was hoping they'd appear in the Network tab of Chrome's developer tools. The closest way I know of is to drop down to Wireshark, but this is fairly cumbersome in comparison. For example, go to http://www.emojitracker.com/ . You'll see the page updating in real time with data from the server, but no activity appears in the network tab. (It subscribes to server events on line 97 of /application.js.) Visit chrome://cache and click on the URL of the server-sent event. Then you will be redirected to a page

I'm trying to stream Server-Sent Events from my Pyramid application, but I can't figure out how to stream the response body from my view. Here's the test view I'm using (it totally doesn't implement SSE, it's just to work out the streaming portion): @view_config(route_name='iter_test') def iter_test(request): import time def test_iter(): i = 0 while True: i += 1 if i == 5: raise StopIteration yield str(time.time()) print time.time() time.sleep(1) return test_iter() This produces ValueError: Could not convert return value of the view callable function pdiff.views.iter_test into a response

I tried an SSE (Server-Sent-Events) using java on tomcat 8.0. Here are few things I noticed. I click a button that automatically makes a request to the servlet. Servlet's GET method gets executed which returns an event stream. Once the full stream is received, the page again automatically makes another request which receives the same data again!!! I don't have an infinite loop there!!! What is actually happening on the server? In normal scenarios, tomcat creates a thread to handle every request. What is happening now? What is the correct way to ensure that the event stream is sent only once to
