ISAPI Extensions

Extensions provide extended functionality to a Web application. These samples illustrate some of the techniques used in creating ISAPI extensions.

For each sample, complete Microsoft® Visual C++® version 5.0 source and project files are provided in the directory indicated.

Simple ISAPI Extension: This sample demonstrates some of the basic features of ISAPI extensions.
ISAPI and COM: This sample demonstrates how to create and use a COM Component with ISAPI.
Keep-Alive: This sample extension demonstrates keep-alive processing.
Worker Thread: This sample is an implementation of a worker thread.
Keep-Alive with Worker Thread: This sample illustrates how keep-alives work with worker threads in an ISAPI DLL.
Server Variables: This example demonstrates how to access and display server variables using ISAPI.
Redirection Extension: This sample shows how an ISAPI extension can redirect browsers.
Synchronous and Asynchronous I/O: This example illustrates how to accomplish synchronous and asynchronous communication using an ISAPI extension.
ISAPI and Forms: This sample shows you how to retrieve information from an HTML form, using ISAPI.
CGI Wrapper: This sample demonstrates how an ISAPI DLL can be wrapped in a CGI executable.
Chunked Transfer Encoding: This sample demonstrates how your ISAPI extension can take advantage of chunk transfer encoding.
