401 unauthorized on IIS 7.5?

[demeter]

Hello,

I cannot make isapi-wsgi-demo work on 64bit Windows Server 2008, IIS
7.5, python 2.7:

"HTTP Error 401.3 - Unauthorized"
Module IsapiModule
Notification ExecuteRequestHandler
Handler AboMapperCustom-50238
Error Code 0x80070005
Requested URL http://localhost:80/isapi-wsgi-demo
Physical Path C:\inetpub\wwwroot
Logon Method Anonymous
Logon User Anonymous

Is the handler name okay? What could be wrong?

BTW, _demo.dll file exists and has no missing dependencies (according
to DependencyChecker).

Thanks

Hi,

Make sure the user name for IIS anonymous access has the permissions to access the directory where the DLL you created for isapi-wsgi-demo was created.

Thanks.

recently)

Another permission related question... I must run isapi-wsgi-demo as
the administrator otherwise I get access denied error when it tries to
register itself. Is it possible to configure IIS so that other users
can call this API too?

Finally, where does stdout/stderr from the WSGI app goes?

When you register a isapi wsgi app, the user running it must have the
IIS permissions to create virtual directories etc. So any user who
creates isapi wsgi apps (it's the same for installing an ASP or .NET
app) would need these additional IIS permissions. They are not
something you would give a normal user.

Regarding stdout & stderr, suggest you read:

http://code.google.com/p/isapi-wsgi/wiki/UnderstandingISAPIWSGI

In the example section, it discusses enabling tracing in the app and
using an external win32traceutil python process as a console to
collect stdout/stderr.
