As the browser receives the Web page , it displays the page to the user. Two different browsers may interpret(that is ,display to the user) a Web page in somewhat different ways. HTTP has nothing to do with how a Web page is interpreted by a client. The HTTP specifications([RFC 1945]and [RFC 2616]) only define the communication protocol between the client HTTP program and the server HTTP program
The steps above use nonpersistent connections because each TCP connection is closed after the server sends the object-the connection does not persist for other objects. Note that each TCP connection transports exactly one request message and one response message. Thus, in this example, when a user requests the Web page,11 TCP connections are generated.
In the steps described above, we were intenyionally vague about whether the client obtained the 10 JPEGs over 10 serial TCP connections , or whether some of the JPEGs are obtained over parallel TCP connections. Indeed, users can configure modern browsers to control the degree of parallelism. In their default modes , most browsers open 5 to 10 parallel TCP connections, and each of these connections handles one request-response transaction. If the user prefers , the maximum unmber of parallel connections can be set to 1, in which case the 10 connections are established serially, As we shall see in the next chapter, the use of parallel connections shortens the response time.
