has_many :bugs, :through => :rails: Introducing Cramp
Cramp is the latest entry on the ruby web frameworks list. However, unlike all the others, Cramp is an asynchronous framework, always running inside EventMachine reactor loop.

Hence itâ€™ll work great for things like comet, long polling, streaming

Comet is a web application model in which a long-held HTTPS request allows a web server to push data to a browser, without the browser explicitly requesting it.[1][2] Comet is an umbrella term, encompassing multiple techniques for achieving this interaction. All these methods rely on features included by default in browsers, such as JavaScript, rather than on non-default plugins. The Comet approac
