Hello.
I'm using libcurl in my project.
I need to upload file over proxy with NTLM auth.
The option for proxy auth is 'ANY':

curl_easy_setopt(curl, CURLOPT_PROXYAUTH, CURLAUTH_ANY);

This is the trace from CURLOPT_DEBUGFUNCTION

I.e. I've got error 55.
You can see body (from line ------------------------------352292fc995c) but there is no response from server.

But if I use Sleep(...) function after send headers like this:

int CPBUpload::TraceFunction(CURL *handle, curl_infotype type, unsigned char *data, size_t size, void *lpParameter)
{
    int i = 0;
    CLogger::Log((LPCTSTR)data);
    switch (type) {
        case CURLINFO_HEADER_OUT:
            Sleep(1);
            break;
...

the file uploaded successfully:

I have success upload also if  I'am set proxy auth as 'NTLM' initially.

May be THIS proxy-server need delay (Wingate 6)?
Thank you.

P.S. Sorry for my english
