How to check on the console for open websockets connections?

Question

I was analyzing how Stackoverflow checks for updates on the question list, but nothing appears on the console (Firebug), so I’m guessing they’re using websockets.

Then I came up with a question: is it possible to check the websockets connections opened through the console (from the browser itself or by Firebug)? How?

Answer 1

If you’re using Google Chrome you can do:

1. Open the Developer Tools window, shortcut: CTRL + Shift + I.

2. Click on the tab Network.

3. Click on the tab WebSockets.

4. Click the button Filter.

   

In the Firebug it is possible to do this from version 2, as quoted in roadmap.
