[python-win32] Please help me find the correct way to call win32inet.WinHttpGetProxyForUrl

I'm trying to use a feature of the Microsoft WinHttp library that has
been exposed by the developers of Win32com. 

Unfortunately most of the library does not seem to be documented and
there are no examples of the correct way to use the win32inet features
via the win32com library.

This is what I have so far:

import win32inet
hinternet = win32inet.InternetOpen("foo 1.0", 0, "", "", 0)
# Does not work!!!
proxy = win32inet.WinHttpGetProxyForUrl( hinternet,
u"http://www.foo.com", 0  )

As you can see, all I am trying to do is use the win32inet feature to
find out which proxy is the appropriate one to use for a given URL, int
his case foo.com.

Can you help me correct the syntax of the last line? MSN has some good
documentation for the function being wrapped (
http://msdn.microsoft.com/en-us/library/aa384097%28VS.85%29.aspx ) but:

* the args do not seem to map the to those of the python library
* and the python win32inet library seems to be missing the constants
which are required in order to call the functions properly. 

Can somebody point me to the correct way to use these objects? Thanks!

I'm using Python2.4.4 with Win32Com on Windows XP.
