Our friend the proxy server

[Trevor DeVore]

I'm interested in hearing what people are doing (if anything) for proxy 
detection on Windows.  Here is the situation I am up against.

I have an app which grabs data from the web on occasion.  Detecting and 
setting proxy settings on Windows is fine if they have manually 
configured IE since the settings show up in the registry.

The big problem occurs when the computers are behind a proxy server and 
the computers are getting their proxy server info automatically from 
the server (from something like a .pac file).  Windows doesn't seem to 
store this info in the registry.

I have a way for users to manually configure their proxy settings but 
in one environment users will be moving to different offices with their 
laptops and proxy settings will change based on their IP subnet.  
Asking these (very) non-technical folks to configure every time they 
movie creates obvious problems.  Anyone have any insight on how to 
detect proxy settings under any circumstances?

Thanks,
