ATL Server is a set of classes to build ISAPI applications in C++. A typical ATL Server project is made up of three major components. The first is an ISAPI extension DLL that implements the required ISAPI methods. In addition, the ISAPI extension provides a thread pool and request-dispatching service to keep the web server responsive.

The second component is the .srf or stencil file. This is a file that contains replacements marked in {{ }} pairs. The .srf file is processed by a request-handler class, usually in a separate DLL. The third component, the request handler, actually processes the HTTP request and implements the replacements used in the .srf files.

ATL Server also provides utility functions to make web development easier. Input validation is supported for numeric ranges and string length, and a regular expression engine is included for sophisticated string analysis. Caching services are also provided to help improve performance in heavily loaded systems.
