HTTP 1.0 to HTTP 1.1

A major improvement in the HTTP 1.1 standard is persistent connections. In HTTP 1.0, a connection between a Web client and server is closed after a single request/response cycle. In HTTP 1.1, a connection is kept alive and reused for multiple requests. Persistent connections reduce communication lag perceptibly, because the client doesn't need to renegotiate the TCP connection after each request.
