The ability of Web applications for allowing businesses to maintain data and services in a central location while also permitting access from anywhere in the world, makes them a highly popular type of application. This chapter presents some suggestions for possible .NET Web application advancements, focusing on AS.NET features and Web services that will enable you to make your applications usable over the Web.
They enable you to apply the same page layout to multiple content pages in a Web application. A master page is essentially astandard ASP.NET page except that it uses the extension of .master and a <%@ master %> directive instead of <%@ page %>. This master page file serves as the template for other pages, so typically it will contain the top-level HTML elements, the main form, headers, footers, and such.
To create an HTTP module, you must implement the IHttpModule interface. The IHttpModule interface has two methods that include the following signatures.
The Init method is called when the module attaches itself to the HttpApplication object and Dispose is called when the module is detached from HttpApplication. The Init and Dispose methods represent the module’s opportunity to hook into a variety of events that are exposed by HttpApplication.
There is not a universal definition of a Web service or a minimum standard for the requirements and services offered by one. What is commonly accepted is that a Web service is a software system that is designed to support interactions between different computers in a network.
The answer to that question involves standardization. With new standards, such as XML and SOAP, you can set the foundation for several platforms and communicate between them. Today, software components can communicate with peers by using a structured language (XML) and through SOAP.
Emerging standards. These include:
Existing standards. These include:
Established standards. These include:

Web Services Enhancements (WSE)
The Web Services Enhancements (WSE) is a .NET class library that augments the .NET Framework and related technologies to provide an implementation of various Web service specifications. WSE is designed to simplify the development and deployment of secure Web services by helping Visual Studio .NET and .NET
