The initial version of HTTP (referred to now as HTTP/0.9) was released in 1991. This initial version of HTTP was based solely on one command named GET. An example GET transaction is shown in Figure 2.4. In the example the client wants to obtain the document named /index.html from the server. The client connects to the server, sends the GET command, and then waits for the server to send the document contents. The server receives the command and sends the client the document, which in this case only contains one line of HTML text.
