Thanks Daniel, it worked fine.

However, i am facing problem with file size more than 65K.
The server expects the Expect: 100-Continue to be set for files more than
size 65K which the libCurl sets on its own.
The network traffic is going through the proxy.
I am using callback functions to send the file.

Using curl.exe, i am able to post files with size more than 65K, but with
libCurl i am getting the error '502 Proxy Error(Network name no longer
valid)' for files of size more than 65K.

I am using read and write callback functions.I am setting the size of the
data and proxy in this way:

curlcode = ::curl_easy_setopt(m_pCurlEasyHandle, CURLOPT_POSTFIELDSIZE,
(curl_off_t)fileStat.st_size);

curlcode = ::curl_easy_setopt(m_pCurlEasyHandle,
CURLOPT_INFILESIZE_LARGE,(curl_off_t)fileStat.st_size);

curlcode = ::curl_easy_setopt(m_pCurlEasyHandle, CURLOPT_PROXY, "
10.55.2.25:8080");

Any guess why this might be happening wehn curl.exe wroks fine with the same
proxy.
