Using Browser Push in Grails | Javalobby


I collected this post here because I want to mark something about Browser Push, which I could find within the post.

Browser Push is the collective term for techniques that allow a server to send asynchronous data updates in near real time to a browser. This article provides an overview of browser push and then provides a sample of Grails usage by extending the example project from the ‘Using JMS in Grails‘ article in the June 2011 edition to send event-driven updates to the browser.

The seconds section is "How does browser Push work?"

Figure 2: Long polling

Figure 3: HTTP Streaming

Figure 4: WebSocket event propagation (HTML5)

It also cover other TERMS of techniques:

• What about Comet / Reverse AJAX?
• Is that the same as Continuations?
• And the Bayeux pub/sub protocol?
• What are the core challenges?
• What Grails plugins are available?

I also like this data flow notation:
