- * mod_isapi.c - Internet Server Application (ISA) module for Apache
- * by Alexei Kosut <akosut@apache.org>
- *
- * This module implements Microsoft's ISAPI, allowing Apache (when running
- * under Windows) to load Internet Server Applications (ISAPI extensions).
- * It implements all of the ISAPI 2.0 specification, except for the
- * "Microsoft-only" extensions dealing with asynchronous I/O. All ISAPI
- * extensions that use only synchronous I/O and are compatible with the
- * ISAPI 2.0 specification should work (most ISAPI 1.0 extensions should
- * function as well).
- *
- * To load, simply place the ISA in a location in the document tree.
- * Then add an "AddHandler isapi-isa dll" into your config file.
- * You should now be able to load ISAPI DLLs just be reffering to their
- * URLs. Make sure the ExecCGI option is active in the directory
- * the ISA is in.
