    Hi There

    Thanks for the quick reply. Your solution may suite perfectly if Windows user explicitly sets proxy server (and port) in IE.

    But in our organization (and most others too) uses auto configuration proxys (proxy.pac).
    In my Windows 7 machine, Under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings, I have

    AutoConfigURL = http://apac.nics.nxp.com:8080/proxy.pac

    I thought of parsing this file and get the real proxy but to me Windows APIs looks simple approach (ofcourse if it works :) ) than parsing .pac file.

    Of course, Your suggestion is also needed for me because few windows user set direct proxy server and port in IE settings but most others have auto proxy config scripts.

    So , What is a best way to get proxy information (Like many installers do , Ex: chrome installer) in windows OS?

    Thanks & Regards,

      Well, if you put it that way :)

      HTTP::ProxyAutoConfig - use a .pac or wpad.dat file to get proxy information

      HTTP::ProxyPAC - use a PAC (Proxy Auto Config) file to get proxy info
