Creating ISAPI Extensions

This section describes how to create dynamic content with ISAPI extensions. ISAPI provides the same functionality as CGI, but can be executed faster than CGI, ASP, and files that call COM+ components. For more information, see ISAPI Extensions.

Complete code samples that include useful ISAPI tools are included with the IIS section of the Platform SDK. These code samples can also bebe downloaded from Platform SDK Update. Many of the topics in this section include example code taken from the complete samples.
