HTTP servers and causing congestion on the Internet. The use of inline images and other associated data often
require a client to make multiple requests of the same server in a short amount of time. Analysis of these
performance problems and results from a prototype implementation are available [26] [30]. Implementation
experience and measurements of actual HTTP/1.1 (RFC 2068) implementations show good results [39]. Alternatives
have also been explored, for example, T/TCP [27].
Persistent HTTP connections have a number of advantages:
?
By opening and closing fewer TCP connections, CPU time is saved in routers and hosts (clients, servers,
proxies, gateways, tunnels, or caches), and memory used for TCP protocol control blocks can be saved in
hosts.
?
HTTP requests and responses can be pipelined on a connection. Pipelining allows a client to make multiple
requests without waiting for each response, allowing a single TCP connection to be used much more
efficiently, with much lower elapsed time.
