I developed a proof of concept application that uses WebSocket to mimic the functionality of Facebook.
If on Facebook someone "likes" a picture, I see the notification on my page right away without me refreshing the page. Is this being done by WebSocket? What strategy is this adopting - pub/sub?
The application I developed is in Java and I came across Atmosphere Framework. I'm not sure which sample I should review from their vast list of examples on GitHub to accomplish what I'm trying to do.
