the trick was not to call again internetopenurl (since it opens a new session), but to call httpsendrequest...

take a look at this example (listed at the bottom of the page) that is shown in MSDN: http://msdn.microsoft.com/en-us/library/aa384220%28VS.85%29.aspx[^]

one would thought that when user name and password are incorrect either in the callback would return proxy_authenticate_error or authenticate will be called again ok i will dig more into it thanks again

One more thing if i may... i was able to work with IAuthenticate implementation (the method 'authenticate' did the trick) problem is that the actual authentication occurs only once, and if the user and password are incorrect i don't reach the method 'authenticate' again. what am i missing wrong here? thanks again

well figured it out... it turns out the 2nd parameter is an out parameter which contains the file that was downloaded and placed in the internet temporary files... so now it works ok thanks myself i guess :)

ok i've digging into it i've found out i can use URLDownloadToCacheFile and set the reserved flag to BINDF_GETNEWESTVERSION this works, but now i have a newer problem that when URLDownloadToCacheFile returns the HRESULT says E_OUTOFMEMORY this is the code i use int nLen = m_sFile.GetLength()* sizeof(TCHAR); HRESULT hr = URLDownloadToCacheFile (NULL,m_sUrl,m_sFile.GetBuffer(nLen),nLen,BINDF_GETNEWESTVERSION,&c); In MSDN it states that if the result is E_OUTOFMEMORY it means that The buffer length is invalid or there was insufficient memory to complete the operation. what am i doing wrong here? thanks for any reply
