Chapter 8. Asynchronous Web Services

IN THIS CHAPTER

• Synchronous Versus Asynchronous Calls

• Design Pattern for Asynchronous Method Calls

• Calling a Web Service Asynchronously

• Server to Server Asynchronous Communications

This chapter will focus on the issues of consuming Web Services asynchronously and the benefits of doing so. Because this book's title references both creating and consuming Web Services, you might be wondering why the focus here will be only on consuming Web Services. That is because there is nothing special that needs to be done to create an asynchronous Web Service. Web services can be consumed either synchronously or asynchronously.

We will examine examples of multiple types of consuming applications, as well as the various techniques for calling Web Services asynchronously.
