[MapProxy] mapproxy IIS

[juergen]

Hi list,

i installed mapproxy under windows in a virtual environment and it works
fine.
In the next step I installed the distribute package with easy install. After
the creation of the yaml files I startet mapproxy with ..\mapproxy-util
serve-develop mapproxy.yaml -b 0.0.0.0:9999 on port 9999 and it works!
Now in the last step I want to deploy mapproxy under IIS port 80.
For that purpose I think installing isapi-wsgi will be the best choice. I
tested the handler with the examples (echo.py etc.) and it works! I only
have to activate the 32bit application setting in IIS, because I'm working
with win7 64bit.
After that I write a config.py:

from mapproxy.wsgiapp import make_wsgi_app
application = make_wsgi_app(r'C:\inetpub\wwwroot\mapproxy\mapproxy.yaml')

import isapi_wsgi
def __ExtensionFactory__():
    return isapi_wsgi.ISAPISimpleHandler(application)

if __name__=='__main__':
	# If run from the command-line, install ourselves.
    from isapi.install import *
    params = ISAPIParameters()
    
    sm = [
        ScriptMapParams(Extension="*", Flags=0)
    ]
    vd = VirtualDirParameters(Name="mapproxy",
                              Description = "mapproxy",
                              ScriptMaps = sm,
                              ScriptMapUpdate = "replace"
                              )
    params.VirtualDirs = [vd]
    HandleCommandLine(params)

and install it with "python config.py"
the response of the shell looks like this:
Configured Virtual Directory: mapproxy
Installation complete.

Everything under IIS looks good. There is an virtual directory and I get
access to the demo page writing "localhost/mapproxy":

Welcome to MapProxy 1.4.0
See all configured layers and services at: demo

However after starting the client mapproxy only produces tile_locks in the
cache directory. I controlled every permission settings in IIS and they will
be ok.
The request header looks like this:

but the reply header gives back:

here are for comparison the working headers using port 9999:

This is the point, where I need help. Is there someone, who knows about
configuring mapproxy for IIS? Notice, we have running mapproxy under linux
and appache and it's no help to launch a discussion about windows.
Every hint is welcome.
