| * 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. |
