Summary: win32trace not working as expected: IIS 7

Initial Comment:
I'm using pywin32-212 on Python 2.5.2 (32-bit) on Windows Vista (64-bit).

I'm trying to wire up a WSGI application in IIS using isapi-wsgi, but I find that the win32traceutil isn't logging anything.

I've started the collector process using: python -m win32traceutil.

I've tested it by running: python -c "import win32traceutil; print 'working'"
and note that the collector prints the string.

I've installed IIS 7 with IIS 6 WMI compatibility.  I've created a 32-bit application pool.  I've created a web site assigned to a 32-bit application pool (called Legacy Development).

Then, I copy isapi/samples/test.py to /inetpub/isapi_test.  I modify it by adding the following to the section indicated by "default response":
            print 'This should show up in the trace util'

Then install the isapi test using:
.\test.py install "--server=Legacy Development"

The app installs correctly, so I browse to http://url.to.the.server/PyISAPITest and I get the default response in the browser, but nothing is logged to the win32trace collector.

I expect that "This should show up in the trace util" should appear in the collector.

What more can I do to investigate/workaround/resolve the issue?

Message:
Further testing confirms this problem does not exhibit itself on IIS 5.1
(Windows XP), so the problem appears to be isolated to IIS 7 (maybe 6) or
Windows Vista.

Message:
I've performed additional testing on a 32-bit Vista machine.  The behavior
is the same... win32traceutil does not receive any output from the ISAPI
process.  Therefore, the problem is not related to the 64-bit platform
aspects.
