From: Alexei Kosut This module is contained in the This module implements the ISAPI
+ Extension API. It allows Internet Server Applications (i.e., ISAPI
+ Extensions) to be used with Apache for Windows.
+
+ In the server configuration file, add a handler called
+ Now simply place the ISA DLLs into your document root, and they will
+ be loaded when their URLs are accessed. ISAPI Extensions are governed by the same restrictions as CGI
+ scripts. That is, Apache's ISAPI implementation conforms to all of the ISAPI 2.0
+ specification, except for the "Microsoft-specific" extensions dealing
+ with ascynchronous I/O. Apache's I/O model does not allow asynchronous
+ reading and writing in a manner that the ISAPI could access. If an ISA
+ tries to access async I/O, a message will be place in the error log,
+ to help with debugging.
+
+ Some servers, like Microsoft IIS, load the ISA into the server, and
+ keep it loaded until memory usage is too high, and it is
+ unloaded. Apache currently loads and unloads the ISA for each
+ request. This is inefficient, but Apache's request model makes this
+ method the only method that currently works. A future release may use
+ a more effective loading method.
+
+ Apache 1.3a1 currently limits POST and PUT input to 48k per
+ request. This is to work around a problem with the ISAPI implementation
+ that could result in a denial of service attack. It is expected that
+ support for larger uploads will be added soon.
+
+ Also, remember that while Apache supports ISAPI Extensions, it does
+ not support ISAPI Filters. Support for filters may be added at a later
+ date, but no support is planned at this time.Module mod_isapi
