(HyperText Transport Protocol-Next Generation) An enhanced version of the HTTP protocol that was developed to meet the increasing performance demands of the 21st century. Explored in a working group of the IETF between 1997 and 1999, it was thought that HTTP-NG would succeed HTTP 1.1 as a more streamlined, layered protocol. Although several proposals were submitted and reviewed, nothing came to fruition. For the latest Activity Statement on HTTP-NG, visit http://www.w3.org/Protocols/HTTP-NG/Activity.html.
