Hi,
  
I'm working with libcurl 7.20.0 (pure C) and trying to upload 16K file with HTTP POST.
I use these options:
  
curl_easy_setopt(m_curl, CURLOPT_POST, 1L);
curl_easy_setopt(m_curl, CURLOPT_POSTFIELDS, fileData);
curl_easy_setopt(m_curl, CURLOPT_POSTFIELDSIZE, fileSize);
  
Also I've defined progress callback with CURLOPT_PROGRESSFUNCTION and expect upload bytes counters there. But I get some incorrect values there.
Here is my debug output:
  
[04/13/10 07:40:18], Sending UploadFile message (12270 bytes) to server
[04/13/10 07:40:18], Uploaded 12270.000000 bytes of 0.000000 bytes
[04/13/10 07:40:18], Uploaded 12270.000000 bytes of 0.000000 bytes
[04/13/10 07:40:19], Uploaded 12270.000000 bytes of 0.000000 bytes
[04/13/10 07:40:20], Uploaded 12270.000000 bytes of 0.000000 bytes
[04/13/10 07:40:20], Uploaded 12270.000000 bytes of 0.000000 bytes
[04/13/10 07:40:20], Uploaded 12270.000000 bytes of 0.000000 bytes
  
I look into the code an I think there is a bug in http.c Curl_http() function.
It doesn't invoke Curl_pgrsSetUploadSize when upload size is for less then MAX_INITIAL_POST_SIZE.
  
Please let me know if it does make sense.
  
Thanks a lot,
Nikita
