Principles, Protocols and PracticesOffers an examination of the core concepts and general principles of web application development, using examples from specific technologies. This book includes coverage of various technologies including: Rapid application approaches Ruby on Rails; Application Primers; and, Search technology.This book provides and in-depth examination of the core concepts and general principles of web application development, using examples from specific technologies. This conceptual knowledge is critical when designing and debugging complex systems, and makes it easier to learn the new application programming interfaces (APIs) that arise in the rapidly changing Internet environment. This book is split into three sections: HTTP protocol as a foundation for web applications; Discussion of markup languages such as HTML, XML and CSS; Survey of emerging technologies. It includes new coverage of technologies including: Rapid application approaches Ruby on Rails; Application Primers; Search technology, including Search Engine Optimization; Simple Object Access Protocol (SOAP); XML Path Language (XPath); Platform for Privacy Preferences (P3P); User-generated content technology for community websites and online collaboration applications; and, Security and encryption.About the Authors.
