Здравствуйте!
Есть вот такой код:

HINTERNET hOpenHandle = InternetOpen(NULL, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);  
    if(hOpenHandle){
        HINTERNET hConnectHandle = InternetConnect(hOpenHandle, "195.***.***.***", 
            83, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 1);  
        if(hConnectHandle){
        //HttpSendRequest(hResourceHandle_auth, hdrs, strlen(hdrs), pBuf, );
                HANDLE hResourceHandle = HttpOpenRequest(hConnectHandle, "POST", "/index.php", NULL, NULL, (LPCSTR*)accept, 0, 1);

            if(hResourceHandle){
                    
                    
                     HttpSendRequest(hResourceHandle, authHdrs, strlen(authHdrs), pAuthBuff, dwpAuthBuff);
//                     InternetCloseHandle(hResourceHandle);
    //                hResourceHandle = HttpOpenRequest(hConnectHandle, "POST", "/index.php?mode=1", NULL, NULL, (LPCSTR*)accept, 0, 1);
                    hResourceHandle = HttpOpenRequest(hConnectHandle, "POST", "/index.php?mode=1", NULL, NULL, (LPCSTR*)accept, 0, 1);
                    HttpSendRequest(hResourceHandle, hdrs, strlen(hdrs), pBuf, dwDataToSend);
        

                
            }
            InternetCloseHandle(hResourceHandle);  
             
        }
        InternetCloseHandle(hConnectHandle);  
    }
    InternetCloseHandle(hOpenHandle);

Авторизация проходит успешно (HttpSendRequest(hResourceHandle, authHdrs, strlen(authHdrs), pAuthBuff, dwpAuthBuff), плюшки приходят нормальные.... далее, следующим SendRequest пытаюсь залить файл который лежит в dwDataToSend. Смотрю в сниффере пакетов. Сперва вывод если я проделываю тоже самое через Оперу:

причём в запросе из оперы там — 00:00:22.890 Opera.exe[2268] (Count=174, Sent=253,62 K, Received=921,87 K, ElapsedTime=2181,719 s)
171 False +34:8.875 s 1,125 s POST 302 542 text/html http://195.***ю***ю***:83/index.php /index.php?mode=1

а у мну:

— 00:35:42.250 SendXMLTest.exe[1140] (Count=2, Sent=50,37 K, Received=2,05 K, ElapsedTime=3,266 s)
176 False +2.640 s 0,625 s POST 200 1,02 K text/html http://195.***ю***ю***:83/index.php?mode=1
