Question about this proxycfg.exe in XP: Does this work for all Internet program? I can get it to work with IE (v6-v7) and CDBurnerXP (to download its update for the program), but not Firefox. I read that the program has to know winHTTP. Am I understanding this correctly? If so, then how do I know which programs support that to do proxy?
The command is born from the fact that MS use more than one 'web access' DLL API for their web backend(s) in Windows XP. IE sets the config for one of the DLL, certain apps (WU amongst them) use the other library. The command syncs the settings used by both DLL, nothing more.

So the result is that various MS software are 'fixed' and start working again with a proxy or after a proxy config is changed. But most non-MS software is not affected.

Thanks. Is there a list of non-MS programs that use this? It seems like
it is WinHTTP API?

I've never seen a full list.

My experience has been that it fixes issues in:
 Windows Update
 Microsoft Update
 early IIS (the ones that could run on 'Home' edition)
 Microsoft Office (including some parts the plugin "Outlook")
 MSN Explorer
 Live Messenger (not 'Window Live Messenger' the older one.)

Though, some of those apps (namely outlook, and Messenger) are able to do certain web requests without it, and require it for others. They only appear partly broken until its done.

And it only is of use on Windows XP. I've just lost the link right now, but there were other (netsh based) methods someone posted this week for Vista and Windows 7.
