    The Hypertext Transfer Protocol , the Web's (请作答此空) protocol , is at the heart of the Web. HTTP is implemented in two programs : a ( ) program and a server program . The client program and server program executing on different end systems , talk to each other by ( ) HTTP messages . HTTP defines how Web clients request Web pages from servers and how servers transfer web pages to clients . when a user ( ) a web page , the browser sends http request messages for the objects in the page to the server . The server ( ) the requests and responds with http response messages that contain the objects .

Howerver, ICMP does not _(73) errors, it simply reports them. Error correction is left to the higher-level potocols. Error messages are always sent to the original__(74) because the only information available in the datagram about the route is the source and destination lP addresses.
