Web Performance Tuning: Speeding up the Web
by Patrick KilleleaAs long as there's been a Web, people have been trying to make it faster. The maturation of the Web has meant more users, more data, more features, and consequently longer waits on the Web. Improved performance has become a critical factor in determining the usability of the Web in general and of individual sites in particular.Web Performance Tuning, 2nd Edition is about getting the best possible performance from the Web. This book isn't just about tuning web server software; it's also about streamlining web content, getting optimal performance from a browser, tuning both client and server hardware, and maximizing the capacity of the network itself.Web Performance Tuning hits the ground running, giving concrete advice for quick results -- the "blunt instruments" for improving crippled performance right away. The book then shifts gears to give a conceptual background of the principles of computing performance. The latter half of the book examines each element of a web transaction -- from client to network to server -- to find the weak links in the chain and show how to strengthen them.In this second edition, the book has been significantly expanded to include:New chapters on Web site architecture, security, reliability, and their impact on performanceDetailed discussion of scalability of Java on multi-processor serversPerl scripts for writing web performance spiders that handle logins, cookies, SSL, and moreDetailed instructions on how to use Perl DBI and the open source program gnuplot to generate performance graphs on the flyCoverage of rstat, a Unix-based open source utility for gathering performance statistics remotelyIn addition, the book includes many more examples and graphs of real-world performance problems and their solutions, and has been updated for Java 2.This book is for anyone who has waited too long for a web page to display, or watched the servers they manage slow to a crawl. It's about making the Web more usable for everyone.

Web Programming with HTML, CSS, and JavaScript
by John DeanWeb Programming with HTML, CSS, and JavaScript is written for the undergraduate, client-side web programming course. It covers the three client-side technologies (HTML, CSS, and JavaScript) in depth, with no dependence on server-side technologies. One of the distinguishing features of this text is its coverage of canvas, one of the most important new features of HTML. Topics are presented in a logical, comprehensive manner and code is presented in both short code fragments and complete web pages, allowing readers to grasp concepts quickly and then apply the concepts in the context of a complete web page. Each chapter concludes with an optional case study, which builds upon itself to create a sophisticated website. The case studies allow students to apply what they have learned and gives them a feel for the real-world design process.
Web Programming with PHP and MySQL
by Max BramerIntroductory textbook covering all the main features of the 'web programming' languages PHP and MySQL together with detailed examples that will enable readers (whether students on a taught course or independent learners) to use them to create their own applications or understand existing ones. A particular focus is the use of PHP to generate MySQL commands from a script as it is executed. Each chapter includes aims, a summary and practical exercises (with solutions) to support learning. Chapters are designed to stand alone as far as possible, so that they can be studied independently of the rest of the text by those with some previous knowledge of the languages. There is a comprehensive glossary of technical terms, together with extensive appendices for quick reference of language features.
Web Proxy Cache Replacement Strategies
by Jake Cobb Hala Elaarag Sam RomanoThis work presents a study of cache replacement strategies designed for static web content. Proxy servers can improve performance by caching static web content such as cascading style sheets, java script source files, and large files such as images. This topic is particularly important in wireless ad hoc networks, in which mobile devices act as proxy servers for a group of other mobile devices. Opening chapters present an introduction to web requests and the characteristics of web objects, web proxy servers and Squid, and artificial neural networks. This is followed by a comprehensive review of cache replacement strategies simulated against different performance metrics. The work then describes a novel approach to web proxy cache replacement that uses neural networks for decision making, evaluates its performance and decision structures, and examines its implementation in a real environment, namely, in the Squid proxy server.
Web Reasoning and Rule Systems
by Balder Ten Cate Alessandra MileoThis book constitutes the refereed proceedings of the 9th International Conference on Web Reasoning and Rule Systems, RR 2015, held in Berlin, Germany, in August 2015. The 5 full papers, 4 technical communications presented together with 4 invited talks were carefully reviewed and selected from 16 submissions. The scale and the heterogenous nature of web data poses many challenges, and turns basic tasks such as query answering and data transformations into complex reasoning problems. Rule-based systems have found many applications in this area. The RR conference welcomes original research from all areas of Web Reasoning and Rule Systems. Topics of particular interest are: answer set programming, complex events, datalog, description logics, event-condition-action rules, information extraction, and logic programming.

Web Searching and Mining (Cognitive Intelligence And Robotics)
by Debajyoti MukhopadhyayThis book presents the basics of search engines and their components. It introduces, for the first time, the concept of Cellular Automata in Web technology and discusses the prerequisites of Cellular Automata. In today’s world, searching data from the World Wide Web is a common phenomenon for virtually everyone. It is also a fact that searching the tremendous amount of data from the Internet is a mammoth task – and handling the data after retrieval is even more challenging. In this context, it is important to understand the need for space efficiency in data storage. Though Cellular Automata has been utilized earlier in many fields, in this book the authors experiment with employing its strong mathematical model to address some critical issues in the field of Web Mining.

Web Service Composition
by Charles J. PetrieThis book carefully defines the technologies involved in web service composition and provides a formal basis for all of the composition approaches and shows the trade-offs among them. By considering web services as a deep formal topic, some surprising results emerge, such as the possibility of eliminating workflows. It examines the immense potential of web services composition for revolutionizing business IT as evidenced by the marketing of Service Oriented Architectures (SOAs). The author begins with informal considerations and builds to the formalisms slowly, with easily-understood motivating examples. Chapters examine the importance of semantics for web services and ways to apply semantic technologies. Topics included range from model checking and Golog to WSDL and AI planning. This book is based upon lectures given to economics students and is suitable for business technologist with some computer science background. The reader can delve as deeply into the technologies as desired.
