WebSockets are rapidly gaining in popularity as a way of enabling full-duplex high-performance communication over a single connection. While they may seem rather otherwordly compared to good 'ol request-response HTTP, they can actually be seen as a subset of actors. Yuvi will give an intro to WebSockets (via Atmosphere) and show how they tightly integrate with Akka by use of Scalatra's extensions. No prior knowledge of WebSockets, Akka, or Scalatra will be assumed.
