ISAPI filter

[Chris Curvey]

Hi all,

I'm trying to write an ISAPI filter in Python, using the examples that
come in the "isapi" directory of the win32com package.  The
installation program itself runs fine, but when I examine the
properties of my web server, my filter has a big red down arrow next to
it.  But I can't seem to figure out where I should be looking to find
the trouble.  If anyone can point me to the right place (or see an
obvious error in the code below), I'd appreciate it.
