Wow! This book is incredible....Until now I had been looking for a good book in IIS and wasn't able to find one then I happned to see this one. I must say it is the most complete IIS book that I have ever found. I have found many chapters that by themselves were worth the price of the book take chapter 4 for example that covers customizing IIS.
In that signle chapter Mr. Stanek provides a detailed guide to understanding how ISAPI/ASP applications works and how you can optimize IIS for various needs. He provides a step by step detailed examination of pooling impact on memory/CPU usage and then details how to customize the environment for pooled and nonpooled applications. After thatm he goes into how you can map custom application extensions, manage session state, control buffering and more. He even details how to unload applications from memory then finishes the chapter by providing a fewe additional customization tips, like how to create an update site that can be displayed while you are updating a primary site, how to create advertising jump pages and how to create customized 404 error pages.
Again, I must say WOW because that is only one chapter in a book filled with such chapters. This book is incredible and the only person that would every say it wasn't is someone who doesn't want other administrators to have these secrets. I use this book to help me manage our corporate web site and I've never found a question that it couldn't answers. I highly recommend this book.
