unicorn: Rack HTTP server for fast clients and Unix
Unicorn é um servidor HTTP para aplicações em rack projetado para atender apenas clientes rápidos em conexões de baixa latência e alta velocidade e tirar proveito dos recursos em kernels tipo Unix / Unix. Os clientes lentos só devem ser atendidos ao colocar um proxy reverso capaz de armazenar completamente o pedido e a resposta entre o licor e os clientes lentos.
