9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * mod_isapi.c - Internet Server Application (ISA) module for Apache
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * by Alexei Kosut <akosut@apache.org>
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz *
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * This module implements Microsoft's ISAPI, allowing Apache (when running
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * under Windows) to load Internet Server Applications (ISAPI extensions).
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * It implements all of the ISAPI 2.0 specification, except for the
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * "Microsoft-only" extensions dealing with asynchronous I/O. All ISAPI
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * extensions that use only synchronous I/O and are compatible with the
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * ISAPI 2.0 specification should work (most ISAPI 1.0 extensions should
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * function as well).
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz *
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * To load, simply place the ISA in a location in the document tree.
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * Then add an "AddHandler isapi-isa dll" into your config file.
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * You should now be able to load ISAPI DLLs just be reffering to their
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * URLs. Make sure the ExecCGI option is active in the directory
9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz * the ISA is in.

9fe74ffcdea85800f04a7222f716f78ae60cce51jerenkrantz    The optimiser blows it totally here. What happens is that autos are addressed relative to the
