Extremely bare example of Spray routing authentication using session cookies and XSRF tokens

This code was quickly ripped out of an active project to serve as an example. It will not compile in any way!

Any questions? Add them to the comments!

Notes

• the application uses a version of the cake pattern to compose the Spray routing application together from various traits
• a lot of those traits should be pretty self-explaining based on their name but if requested I can paste them into this Gist

Akka Cluster Implementation Notes

Slightly disorganized but reasonably complete notes on the algorithms, strategies and optimizations of the Akka Cluster implementation. Could use a lot more links and context etc., but was just written for my own understanding. Might be expanded later.

Links to papers and talks that have inspired the implementation can be found on the 10 last pages of this presentation.

  def flatMap[U](fn: T => Transaction[U]): Transaction[U] =
    FlatMapped(this, fn)
