The Rocket web server is a server designed to handle the increased needs of modern web applications implemented in pure Python. It can serve WSGI applications and static files. Rocket has the ability to be extended to handle different types of networked request-response jobs. Rocket runs on cPython 2.5-3.x and Jython 2.5 (without the need to run through the 2to3 translation tool). Rocket is similar in purpose to Cherrypy's Wsgiserver but with added flexibility and concurrency.
