I need to download a file from a server and my problem is that the size of the file is wrong.  Here's my code:

pHttpFile = (CHttpFile*)(session.OpenURL( "http://netdev1/~foo/bar/bar.ini"));

pHttpFile->SendRequest("", NULL, 0);

DWORD dwStatus;
pHttpFile->QueryInfoStatusCod(dwStatus);            

if (dwStatus < 200 || dwStatus > 299)
      AfxThrowInternetException(pConnection->GetContext());

CString csFilename = APPINFO->GetAppRootPath() + "bar.ini";
                  CFile fileLocal(csFilename,
                        CFile::modeCreate | CFile::modeWrite);

int iLen = pHttpFile->GetLength();
BYTE* pBuf = new BYTE[iLen];
pHttpFile->Read(pBuf, iLen);

fileLocal.Write(pBuf, iLen);
fileLocal.Close();

pHttpFile->Close();

The problem is that the GetLenght method does not return the right size but the file is all here because if I change the value of iLen before it is used and set it to the right size everything is fine!

BTW, the size returned seems to be pretty random but around 700 bytes...

Your code is not right.

Casting the return value of CInternetSession::OpenURL() is the wrong thing to do.

Calling SendRequest() on the file returned from OpenURL() is wrong, as well.

You can either:

1) Remove the cast. Remove the call to SendRequest().

or

2) Call CInternetSession::OpenHttpConnection(). Call CHttpConnection:OpenRequest(). Call CHttpFile::SendRequest().
