ref: H2O version 1.4.0 released with outstanding support for forward secrecy and load balancing (and the experimental mruby handler), http://blog.kazuhooku.com/2015/07/h2o-version-140-released-with.html Developed by Yukihiro Matz (the father of the Ruby programming language) and others, mruby is an implementation of the language for embedded use. Thanks to MATSUMOTO Ryosuke the language runtime can now be used to script how the HTTP requests should be handled within H2O. Please refer to Ryosuke's weblog for more information (in Japanese). In addition to topics related to H2O, you can find excellent entries about how to use a scripting engine within web servers to work against cyber attacks.
