NET frame-work, known as the. NET avoids this problem by using a just-in-time JIT compiler, which is generally transparent to the user. NET can be calledfrom a C application and vice versa. Whereas a privately addressedcomputer can initiate a request for information from a foreign computer,no foreign computer can initiate a request for information from a privatelyaddressed computer.

How to: Send Data Using the WebRequest Class

The open systems interconnection OSI network stack modelhas seven layers of encapsulation, as shown in Table 1.

You can make an asynchronous request to the Internet resource using the HttpWebRequest. Seasoned programmers may skip the first chapter, and readerswill quickly find the pace fast enough to keep even the most expert develop-ers glued to the pages. This is called the hardware, or media accesscontrol MAC address.

Failure to close the stream causes your application to run out of connections. Class B holds 65, public IPaddresses.

No other changes are needed. Without the concept of encapsulation, programmerswould quickly become bogged down with insignificant details.

NET, and as such it isassumed that you already know basic programming constructs such as if statements and loops. Both languages have exactly the same capabilities, andthere is absolutely no difference in performance between the two languages.

Form must be created in order for there to bea visual interface. In fact both those method get a response and read it and deal with the exceptions - this is duplicated code which you should move into a dedicated function which you can then call from both main methods like this: Although the capabilities of Web sites and network programs arequickly converging, it is important to understand the arguments for andagainst each system.

This IP address always refers to the local machine and isused in later examples. A network program is any application that uses a computer network totransfer information to and from other applications.

NET developers to be aware of the code that is autogener-ated by Visual Studio. A computer may not always have the same IP address. If you share your Internet connection with other computers on yournetwork, you may have a private IP address.

You can access the properties of the WebResponse or cast the WebResponse to a protocol-specific instance to read protocol-specific properties. Only one of thoseIP addresses is publicly accessible.

This section shows you how to write and compile a.

If the scheme for the URI is http: Whenever a class is created, a function known as the constructor is called. Inreal-world applications, networking code is generally kept separate fromother facets of the application e. Therefore, you may also experience slow performance on the computer and in other applications because increased memory and resource utilization occurs.

PreAuthenticate property to true. The latter isthe only namespace of the three that is actually supplied by the program-mer. Although the book is geared for developers, as a solution architect, ITmanager, or even computer science undergraduate, you will also find thisbook of enormous benefit.

No part of this publication may be reproduced, stored in a retrieval system, or transmitted in any form or by any means, electronic, mechanical, photocopying, recording, or otherwise, without the prior written permission of the publisher. The bene-fits of such an architecture are security and the possibility for load balanc-ing, which is described in more detail in later chapters.
