State management has always been a complex and tricky part of web application development. Continuations simplify this and automatically allow you to create a one-to-one conversation between users and a web application. State preservation and flow control no longer need to be handled manually, bringing you back to the simplicity of single user console applications. Remember 'scanf()'?

This presentation will introduce continuations from general principles, followed by practical examples that explain how they benefit web application development and their frequent usage patterns. Finally, automatic fail-over and scalability will be demonstrated through the integration with Open Terracotta.
