A description and analysis of the vulnerabilities caused by programming errors in Web applications, this book is written from both from the attacker's and security specialist's perspective. Covered is detecting, investigating, exploiting, and eliminating vulnerabilities in Web applications as well as errors such as PHP source code injection, SQL injection, and XSS. The most common vulnerabilities in PHP and Perl scripts and methods of exploiting these weaknesses are described, information on writing intersite scripts and secure systems for the hosted sites, creating secure authorization systems, and bypassing authorization. Uncovered is how attackers can benefit from the hosted target and why an apparently normal-working application might be vulnerable.

Regular Expressions are an essential part of programming, but they can be hard to come to grips with. Regular Expression Recipes for Windows Developers contains over 100 of the most popular regular expressions, along with explanations of how to use each one. Languages covered include JavaScript, VB, VB.NET, and C#.
The author provides concise syntax references as needed, and enables the reader to learn more about regular expressions by example. Web and applications developers will find the examples in this book accurate and relevant. This book will be an ideal solutions guide for a developer or systems administrator to keep in a handy place for quick reference.

The i-Net+ exam was developed for the millions of job seekers who want to stand up tall and shout, “Hey! You! Companies! I know something about the Internet, so hire me for oodles of money!” And after you read the new Sybex i-Net+ Study Guide and pass the exam–because you will pass if you read this book thoroughly–you too will be able to join in the joy and revelry that comes with being one of those mysterious wizards who Understands The Net.

Okay… maybe it’s not that great. (For one thing, the secret handshake we Internet wizards have gives you all sorts of nasty cramps.) But it is a laudable and well-written overview of the basic issues involved in working with the Web, which is exactly what the i-Net+ is testing for–and whether you’re a long-term Net junkie checking your knowledge before the exam, or just a novice looking to position yourself for better and bigger things, this book will serve you very well.
Given the breadth of the topics that need to be covered, the guide is succinct but thorough.

Amazon.com is advancing the boundaries of the Internet through their powerful suite of web services. Innovative developers are combining Amazon data with other freely available sources to create new and interesting applications known as Mashups. This book teaches you the techniques behind mashup applications and for the first time shows you how to build them yourself.

The examples in this book show you how to integrate Amazon web services with APIs from Yahoo!, eBay, Google and YouTube. You’ll learn how to combine data from disparate sources to create new applications using next generation browser techniques such as AJAX, JSON and Dynamic Scripting. You will learn how to re-purpose web service data so that it can be consumed from mobile devices such as a cell phone or PDA. Because both the theory and code are explained, you’ll be able to easily take the lessons in this book to build your own killer mashup applications.

Start planning to transition to IPv6 internetworking and find out all about the next-generation Internet—from its features and benefits to its packet structure and protocol processes. This book is a straightforward discussion of the concepts, principles, and processes of Internet Protocol version 6 (IPv6) and how IPv6 is supported by the Microsoft Windows .NET Server 2003 family of operating systems. It is primarily a discussion of protocols and processes rather than a discussion of planning, configuration, deployment, and management. It is also mostly about IPv6 rather than the specifics of the implementation for the Windows .NET Server 2003 family. Therefore, this book does not contain in-depth implementation details of the IPv6 protocol for the Windows .NET Server 2003 family, such as structures, tables, buffers, or coding logic. These details are highly guarded Microsoft intellectual property that is of interest only to a relative handful of software developers. The purpose of this book is to provide an educational vehicle that will enable one to learn IPv6 to a fair technical depth—the terms, the addresses, the protocols, and the processes. This is not intended to be a breezy marketing overview of IPv6 and how it "provides integrated and interoperable technologies to enable exciting new scenarios for personal and enterprise computing."

I will leave that type of documentation to those who are much better at it than I am. The bottom line is that I am a protocols and processes person. My main concern and interest is how the protocols work and what one sees on the wire (what packets are exchanged), and these topics comprise the bulk of this book.

Ruby on Rails is the revolutionary online programming tool that makes creating functional e-commerce web sites faster and easier than ever. With the intuitive, straightforward nature of Ruby and the development platform provided by Rails, you can put together full-fledged web applications quickly, even if you're new to web programming.

You will find a thorough introduction to both Ruby and Rails in this book. You'll get the easy instructions for acquiring and installing both; understand the nature of conditionals, loops, methods, and blocks; and become familiar with Ruby's classes and objects. You'll learn to build Rails applications, connect to databases, perform necessary testing, and put the whole thing together to create real-world applications such as shopping carts and online catalogs–apps you can actually use right away.

What you will learn from this book
* How to install and use Ruby and Rails
* Object-oriented programming with Ruby
