Proxy Authentication error

[ami]

Hello everyone,



I have a connection made to the internet :-

CInternetSession session;
session.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT, 1000);
session.SetOption(INTERNET_OPTION_CONNECT_RETRIES, 3);

try
{
remoteFile = session.OpenURL(urlPath, 1 ,
INTERNET_FLAG_TRANSFER_BINARY |
INTERNET_FLAG_RELOAD |
INTERNET_OPEN_TYPE_DIRECT );

}
catch (CInternetException)
{
AfxMessageBox("Received Exception from OpenURL()");
// Handle exception
}

This all works fine, and then I wish to download the file using :-

if (remoteFile == NULL)
{
cout << "Error in OpenURL";
}
else
{
cout << "Ok in OpenURL";
// Read from file

while (nBytesRead = remoteFile->Read(inBuf, sizeof(inBuf)))
{
...
}

When I run the software at home all works fine and the file (Excel) is downloaded successfully.

However, at work I'm getting Proxy Authentication error, i.e. the software cannot go out through the gateway.

The Windows Administrator tells me that if I can type the URL in IE browser and a pop-up comes up with Save As, Open etc, and later the file is downloading, then it must be my process. However, as I said this works at home ok.

Also, I should mention that when I use the same process at work (or home) to point to URLs ending with .html (obviously no dialog boxes appear), then all ok.

FYI: whether I try to download the file manually or using the automated process - in both cases I'm logged to the server as the same user who has permissions to download files from the Internet.

Any ideas what it might be ? Is OpenURL, or remoteFile->Read works differently from html to Excel files ?

Many thanks.

you need to also give your proxy username and proxy password to your call
CHttpConnection* GetHttpConnection(
LPCTSTR pstrServer,
INTERNET_PORT nPort = INTERNET_INVALID_PORT_NUMBER,
LPCTSTR pstrUserName = NULL,
LPCTSTR pstrPassword = NULL
);
