阅读更多关于 How RSS and ATOM inform client about updates? long polling or polling or something else?

问题 I read that RSS and ATOM are HTTP-based using XML format. So how an RSS or Atom reader get informed about content updates if HTTP doesn't support connections? Do they need to poll the server periodically? I'm interested in using it in a real time web application but I heard that "polling doesn't scale". 回答1: This is pretty similar to this question. Please read my answer there. There is no currently long polling for RSS feeds. The technology you're looking for is PubSubHubbub : it will allow

I have subscribed my server to my Youtube channel via youtube PubSubHubbub. I am experiencing delay in notifications sometimes. Is there anyway ( like statistics, tracking, youtube API ) by which I can know, when the PubSubHubbub event is fired, so that I can actually know, if there is a delay? .

问题 I'm currently building a live web application based upon the PubSubHubBub protocol. However, I encountered several issues. First, I'm in search of a hub application that I can run on my server. There are several applications, but most of them are not mature yet, or they don't support the 0.3 spec. The official google hub runs on the Google App Engine and can even be executed locally.
