Now in the Fourth Edition, Programming the World Wide Web provides a comprehensive introduction to the tools and skills required for both client- and server-side programming, teaching students how to develop platform-independent sites using current Web development technology. Essential programming exercises are presented using a manageable progression: Students begin with a foundational XHTML Web site and employ new languages and technologies to add features as they are discussed in the course. Readers with previous experience programming with an object-oriented language are guided through concepts relating to client-side and server-side programming, including ASP.NET using C#, JavaScript,Java servlets, Ajax, JSP, XHTML, XML, Perl, PHP, Ruby, and Ruby on Rails.
