21.1. Introduction

In Chapter 20, we introduced ASP.NET and web application development. In this chapter, we introduce several additional ASP.NET web-application development topics, including:

• master pages to maintain a uniform look-and-feel across the Web Forms in a web application

• creating a password-protected website with registration and login capabilities

• using the Web Site Administration Tool to specify which parts of a website are password protected

• using ASP.NET Ajax to quickly and easily improve the user experience for your web applications, giving them responsiveness comparable to that of desktop applications.
