CInternetException 内存泄漏

在用WinInet, Post文件倒服务器上时候只要给的服务器的url不存在,比如 www.xxx.fuck就会产生例外,同时伴随内存泄漏, 我怎么也找不到哪里泄漏了代码如下:
---------------------------------------------
// Post data to server
// url indicates the relative path to the server, "/foo.asp"
BOOL CMyHttps::PostTextFile(CString &text, CString filename, CString strServiceName, CString url, CString &response)
{

return PostFile(text.GetBuffer(), iLen, _T("text/plain"), filename, strServiceName,  url, response);
} BOOL CMyHttps::PostFile(TCHAR *pFileToUpload, int iFileLen, CString filetype,
CString filename, CString strServiceName, CString url, CString &response)
{
if(!m_pConnection)
return FALSE; try
{

url, NULL, 1, NULL, NULL, dwFlags); CString strHTTPBoundary = _T("IllBeVerySurprisedIfThisTurnsUp");
CString strPreFileData = MakePreFileData(strHTTPBoundary, filename, strServiceName, filetype);

strPreFileData.GetLength() +
strPostFileData.GetLength() + iFileLen; if(pFile)
{
pFile->AddRequestHeaders(MakeRequestHeaders(strHTTPBoundary));
BOOL bRequestOK = pFile->SendRequestEx(dwTotalRequestLength, HSR_SYNC | HSR_INITIATE); if(!bRequestOK)
{
pFile->Close();
delete pFile;
return FALSE;

{
