Behind every web transaction lies the Hypertext Transfer Protocol (HTTP) --- the language of web browsers and servers, of portals and search engines, of e-commerce and web services. Understanding HTTP is essential for practically all web-based programming, design, analysis, and administration.While the basics of HTTP are elegantly simple, the protocol's advanced features are notoriously confusing, because they knit together complex technologies and terminology from many disciplines. This book clearly explains HTTP and these interrelated core technologies, in twenty-one logically organized chapters, backed up by hundreds of detailed illustrations and examples, and convenient reference appendices. HTTP: The Definitive Guide explains everything people need to use HTTP efficiently -- including the "black arts" and "tricks of the trade" -- in a concise and readable manner.In addition to explaining the basic HTTP features, syntax and guidelines, this book clarifies related, but often misunderstood topics, such as: TCP connection management, web proxy and cache architectures, web robots and robots.txt files, Basic and Digest authentication, secure HTTP transactions, entity body processing, internationalized content, and traffic redirection.Many technical professionals will benefit from this book. Internet architects and developers who need to design and develop software, IT professionals who need to understand Internet architectural components and interactions, multimedia designers who need to publish and host multimedia, performance engineers who need to optimize web performance, technical marketing professionals who need a clear picture of core web architectures and protocols, as well as untold numbers of students and hobbyists will all benefit from the knowledge packed in this volume.There are many books that explain how to use the Web, but this is the one that explains how the Web works. Written by experts with years of design and implementation experience, this book is the definitive technical bible that describes the "why" and the "how" of HTTP and web core technologies. HTTP: The Definitive Guide is an essential reference that no technically-inclined member of the Internet community should be without.

This book is about managing the security of IT services in terms of organization, orchestration, and optimization. It compresses the complex subject matter into individual terms and their definition, and it exploits systematics and terminology to create order, illuminate relationships, and provide concrete support for implementing IT service security successfully and with an eye for the essentials. The book describes a management system called ESARIS (Enterprise Security Architecture for Reliable ICT Services) with field-proven methods and recipes. This metasystem or security architecture builds on more than a decade of day-to-day experience in the IT industry with multi-national customers. To enable the reader to fully exploit the guidance given, explicit definitions are provided for about 75 terms that can be used to look up a topic. Numerous figures and tables further support orientation and understanding, together with detailed introductions and explanations they offer a comprehensive presentation of IT service security issues and solutions. This book is written for professionals with IT service providers (including IT departments), user organizations (including business units) or manufacturers, vendors, and suppliers.

Addresses cryptography from the perspective of security services and mechanisms available to implement them. Discusses issues such as e-mail security, public-key architecture, virtual private networks, Web services security, wireless security, and confidentiality and integrity. Provides a working knowledge of fundamental encryption algorithms and systems supported in information technology and secure communication networks.

Presents recommendations, analysis, and process descriptions intended to redefine, broaden, and make more meaningful the ongoing efforts of the Arizona Electronic Highway Users Group. Addresses telecomm. trends and resources for local gov't., model telecomm. ordinances, right-of-way coord., licensing/franchising and revenue stream protection, locating and permitting wireless providers, emergency/public safety commun., telecommuting and teleconf., public electronic access to info. and services, e-mail and Internet use policy, computer security, ergonomics and human factors, info. tech. mgmt., year 2000 software issues, etc.

IP Multimedia Subsystem (IMS) technology, which merges the Internet with interactive telecommunications, represents the here and now for today's packet-switched networks. Consequently, anyone working with or around these converging fields needs to possess a fundamental understanding of IMS and how this technology is poised to change the way new app
