    Hi guys.

    I’m currently on a new project where i’m building a forum – and chatsystem. When i go and look into facebooks networktab in google chrome it dosen’t send ajax request all the time. It only requests when there is a new message and I was wondering if you guys could help me doing the same?

    Thank you :D


    I’m guessing they use , with a fallback since browser support isn’t that good.
