Overview of this book

Microsoft Forefront Unified Access Gateway (UAG) is the latest in a line of Application Publishing (Reverse Proxy) and Remote Access (VPN) Server products. The broad set of features and technologies integrated into UAG makes for a steep learning curve. Understanding all the features and abilities of UAG is a complex task that can be daunting even to experienced networking and security engineers. This book is the first to be dedicated solely to Microsoft Forefront UAG. It guides you step-by-step throughout all the stages of deployment, from design to troubleshooting. Written by the absolute experts who have taken part of the product’s development, official training and support, this book covers all the primary features of UAG in a friendly style and a manner that is easy to follow. It takes you from the initial planning and design stage, through deployment and configuration, up to maintenance and troubleshooting. The book starts by introducing UAG's features and and abilities, and how your organization can benefit from them. It then goes on to guide you through planning and designing the integration of the product into your own unique environment. Further, the book guides you through the process of publishing the various applications, servers and resources - from simple web applications to complex client/server based applications. It also details the various VPN technologies that UAG provides and how to take full advantage of them. The later chapters of the book educate you with common routine “upkeep” tasks like monitoring, backup and troubleshooting of common issues. Finally, the book includes an introduction to ASP, which some of the product's features are based on, and can help the advanced administrator with enhancing and customizing the product.

What are Regular Expressions?


Regular Expressions are a formal, or syntactical, language, used to create strings of text, which define a search pattern. The writer of a regular expression has the choice to create a regular expression as specific or as relaxed as he wishes, meaning that it could match only a very specific piece of text, or it could possibly match many text strings, as long as all of them follow the same pattern described by the regular expression. Many programs and programming languages contain a RegEx processing engine, which allows the programmer to define patterns, rather than specifying exact strings for everything. A regular expression is a piece of text that contains regular characters, known as literals, and special characters, known as non-literals. You can think of non-literals as 'commands' that tell the engine to do something special. For example, the regular expression tal[cekly] means something that starts with tal and ends with either c, e, k, l or y. We are using just 10 characters to describe 5 distinct words!
