Undertow, the web server in WildFly, has added support for the new HTTP/2 standard. HTTP/2 reduces latency by compressing headers and multiplexing many streams over the same TCP connection. It also supports the ability for a server to push resources to the client before it has requested them, leading to faster page loads. We also included support for SPDY, the predecessor to HTTP/2, in order to support clients that have not yet updated to the new specification. Although, currently, recent versions of Chrome and Firefox provide support for the standard out of the box.
