Many APIs  
Roy Fielding proposed the Waka system as a "binary token-based" replacement for this system to improve upon its inefficiencies. This system's 2.0 version is based on the SPDY  (speedy)  standard and uses multiplexing for increased performance over its widely-used 1.1 version. Many APIs  (A-P-I's)  implement some of the verbs introduced in this system, such as "delete", "post", and "put". Requests sent using this standard may give a "client" a piece of data known as a (*)  cookie. This protocol was first implemented by Tim Berners-Lee in 1991. To indicate that a resource is not found, this protocol returns the "404" status code. For 10 points, name this protocol used to move web pages and other data across networks, which has a four-letter abbreviation.
