The book will also contain case studies to illustrate real-world examples of specific topics.CF4 is a massive upgrade, and it adds lots of new features, all of which are advanced. Basic CF does not change much, but things such as the support for server clusters, security frameworks, etc., are complicated subjects, and will be discussed in detail in this book. This book will address these issues and technologies, including: Using clustering and failover technologies to ensure server uptime; Server monitor and benchmarking; Creating secure applications, and integrating with existing security systems; Extending Cold Fusion using COM/DCOM, CORBA, JavaBeans, and the Cold Fusion C and Delphi API's; Customizing and modifying the client environment; ISP Cold Fusion hosting issues; and Working with XML.
