    Download File through HTTP Proxy

    All my university's internet traffic goes through an HTTP proxy. What I need to do is download XML files from certain websites, but before I can access these websites I need to authenticate through the proxy.

    Basically what I'd like to find out is how to go about getting my program (C++) to use IE settings (where the proxy details have been entered), then popup an authentication screen and if that's valid then retrieve the file.

    Any ideas?

    Have you looked into the WinInet API ?

    IE uses WinINet, not the other way around, so that wouldn't work.

    There might me some reg keys pertaining to what you want.

    Sounds like an incredible mission. Surely there's some way of going about this, as there are lots of commercial apps that can update through a proxy etc.

    You could monitor IE with this while changing the proxy settings. You might find a key(s) that way.

    Actually I've been experimenting with the IE registry (especially with proxy handling) and I wrote down the key needed:

    Code:
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
    The REG_SZ "ProxyServer" defines the Proxy server as an "address:port" type, the REG_DWORD "ProxyEnable" is set to 1 if the proxy is enabled in IE (0 otherwise).

    If you call InternetOpen with INTERNET_OPEN_TYPE_PRECONFIG, WinINet will use these values, as explained in 'setting access types'.

    You can set the proxy username and password using InternetSetOption as explained in 'proxy authentication'.
