"My books are like water; those of the great geniuses are wine. (Fortunately) everybody drinks water."
āMark Twain
The aim of this book is to comb through the many features of Citrix Application Delivery Controller, which is NetScaler, and give you insight into how to handle and tune them according to your requirements.
I have tried to whip up as many recipes as possible so that they would be easier for readers to choose from. In addition, there are certain important terms explained, which we usually come across while deploying Citrix NetScalers and Access Gateways, but don't think much about. By the end of this book, we hope to give readers a good practical knowledge of the working of an end-to-end Citrix solution. Though it is recommended you read it from start to finish, it is made flexible so that you can move between recipes and skip to recipes that intrigue you.
This book will also try to simplify any complexities involved and make the read an interesting one.
