Internet and web technologies are the resources that support web browsing and client and server applications. Developers can use these technologies to display web content on the desktop and iPhone, and they can use web services in their desktop applications. With WebObjects, developers can create database-driven websites and web services. Developers have access to Java technologies and to low-level APIs for handling XML and URLs. Developers create web content using HTML, XHTML, CSS, JavaScript, DOM, and AJAX/Web 2.0.

A guided introduction and learning path to developing for web and Internet.   Essential information for creating Internet and web applications, services, or content.   Objective-C and C references organized by framework.
