The http/1.0 protocol uses a non-persistent connection , that is, under non-persistent connections , a TCP connection transmits only one Web Object .
http/1.1 uses persistent connections by default . in a TCP the connection can be routed over multiple HTTP requests and responses, reducing the consumption and latency of establishing and closing connections
However , the client and server of the http/1.1 protocol can be configured to use non-persistent connections

HTTP 1.1 also improves and expands the functionality of HTTP 1.0 by adding more request headers and response headers. After adding the host Request header field to HTTP 1.1, the Web browser can use the host header name to explicitly indicate which Web site to access on the server, which enables multiple virtual Web sites to be created on a single Web server with a different hostname on the same IP address and port number
