Chapter 1, Architecture, covers the fundamentals of the ASP.NET architecture, beginning with a look at the parsing of .aspx files and their subsequent compilation into assemblies. This chapter explains the details of the Page class, demonstrates the new code-behind model, and discusses the shadow copy mechanism used to prevent file locking. The chapter concludes with a look at the new classes in ASP.NET that replace the intrinsic objects of traditional ASP.Chapter 2, Web Forms, looks at the control-based programming model supported in ASP.NET called Web Forms. This chapter looks at the details of state retention across post-backs using both POST body data and View-State, and describes how to effectively use server-side controls to create dynamic Web pages. The chapter concludes with a look at the various server-side controls available in ASP.NET.
Chapter 3, Configuration, describes the configuration model used by ASP.NET, starting with the XML format used by all configuration files and the hierarchical application of configuration settings. This chapter inspects several configuration elements in detail, including the processModel and appSettings elements. The chapter concludes by demonstrating two techniques for adding custom configuration sections to your configuration files.
Chapter 4, HTTP Pipeline, explores the details of the classes involved with servicing HTTP requests in ASP.NET. This chapter first walks through all the elements in the HTTP pipeline used to process a request, and then discusses the three points of extensibility in the pipeline: custom application classes, custom handlers, and custom modules. The chapter concludes with a discussion of threading and object pooling in the pipeline.
Chapter 5, Diagnostics and Error Handling, covers the new diagnostic features of ASP.NET, including page and application tracing as well as the new performance monitor counters. This chapter also discusses techniques for debugging ASP.NET applications and exception handling. The chapter concludes with a look at how to define custom error pages for your applications.
Chapter 6, Validation, describes the new validation architecture built into ASP.NET. This chapter begins by looking at how validation is performed in Web applications in general and proceeds to show how ASP.NET's validation architecture provides a general solution to the problem of validating user input. The chapter includes a detailed look at how both client-side and server-side validation work, as well as a look at all the available validation controls.
Chapter 7, Data Binding, explores the process of binding server-side data to controls in an ASP.NET page. This chapter starts by explaining how data binding works with several different data sources, including collection classes, DataReaders, and DataSets, and then looks at how to bind data to several controls, including the DataGrid class. The chapter concludes with a look at templates and how to use them effectively with the Repeater, DataList, and DataGrid classes.
Chapter 8, Custom Controls, covers the fundamentals of building your own custom controls for use in ASP.NET applications. This chapter explains how custom controls are built, how to use the HtmlTextWriter class to achieve some browser independence, how to further support browser-independent rendering, how to define properties and subproperties, how to extract the inner content of a control's tag, how to generate client-side script, and how to manage control state. The chapter also covers the details of building composite controls, user controls, controls that support validation, and controls that support data binding. The chapter concludes with a look at how to integrate your controls with the Visual Studio .NET designer.
Chapter 9, Caching, looks at both output caching and data caching in ASP.NET. This chapter discusses the mechanism of output caching and how to precisely control which versions of a page are placed in the cache, as well as how to cache portions of a page using page fragment caching with user controls. The chapter explains how to use the new application-wide data cache and includes a discussion of considerations and guidelines to observe when caching data.
Chapter 10, State Management, discusses the various types of state in an ASP.NET Web application and how and when to use each type. This chapter begins with a look at application state and explains why it should typically be avoided in ASP.NET. It then looks at the improvements in session state, including out-of-process storage and cookieless key management, as well as techniques for optimizing your use of session state. The chapter concludes with a look at using cookies and view state as alternatives, or in addition, to session state.
Chapter 11, Security, describes the security features of ASP.NET and how to control client authentication and authorization in your applications. This chapter starts by reviewing the concepts of security for Web applications and then shows how to build and manage applications that need to authenticate clients using the forms authentication architecture provided by ASP.NET. The chapter also covers the management of authentication cookies in Web farms, safe password storage, building role-based authentication systems, and how to control the process identity used by ASP.NET.
