Description:
Rack HTTP server for fast clients
Unicorn is an HTTP server for Rack applications designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix and Unix-like kernels. Slow clients should only be served by placing a reverse proxy capable of fully buffering both request and response in between Unicorn and slow clients.
