 Jetty's goal is to support web protocols (HTTP/1, HTTP/2, HTTP/3, WebSocket, etc.) in a high volume low latency way that provides maximum performance while retaining the ease of use and compatibility with years of Servlet development.
 Jetty is a modern fully asynchronous web server that has a long history as a component oriented technology, and can be easily embedded into applications while still offering a solid traditional distribution for webapp deployment.
