Messages,
Workers, and
Sockets

WEB MESSAGING,
Web Workers, and Web Sockets are
all different APIs but all have the same communication
API, which is why I will show you all three together. Only
the Messaging API is part of the official HTML5 spec,
but all three of these APIs are valuable additions to any
web application.
Messaging allows for sending messages from one domain
to another, something that Ajax security policies have
long prevented—for good reason—but is now starting to
open up with the right security measurements in place.
