Polling for database changes?
I am slightly confused and overwhelmed. I would like to set up a notification system on my web application. I have found lots of quick snippets of polling, but nothing that really shows me how to put it all together.
How do I fire the alert? What do I check for on my server side page? How do I tie the polling into a notification? These are some of the questions I just can't find any answers or examples for.
Can anyone help?? :D
Google "web sockets" and "long polling".
i would use EventSource if i were you, it's way easier than sockets on the backend (its just http), and way less sucky than ajax2 or jsonp long-polling.
