[lucky2all]

保证用户有对/log路径的写权限，
在up文件时，出现
12032 ERROR_INTERNET_FORCE_RETRY
Calls for the Win32 Internet function to redo the request.
错误，
不知是何原因，请大虾指点！！！！

strUpload = "/log";
strUpload += "/mail.htm";

CInternetSession IsvSession("hello");
IsvSession.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT, 100);
m_pIsvConnection = IsvSession.GetHttpConnection("yangsong",
80, "hnjh", "hnjh");
m_pIsvHttpFile = m_pIsvConnection
->OpenRequestCHttpConnection::HTTP_VERB_PUT, strUpload);

CString strData = "Some very long data to be POSTed here!";

BOOL bSend = m_pIsvHttpFile->SendRequestEx(strData.GetLength());
m_pIsvHttpFile->WriteString(strData);
m_pIsvHttpFile->EndRequest();
