Btw, the below option worked but it started to fail after the content length
was 1002. Is there any limit to how much data you can post using postfields
option or some tweak is needed here?

As an alternative, I tried using this
http://curl.haxx.se/mail/lib-2006-07/0218.html, but doing this, the
content-type I am setting is not sent correctly to the services and
something internally is being sent.. The way I am using it is.

 curl_formadd(&post, &last, CURLFORM_COPYNAME, "request", CURLFORM_BUFFER,
"test", CURLFORM_BUFFERPTR, buff, CURLFORM_BUFFERLENGT
H, bs->size(), CURLFORM_CONTENTTYPE, "application/test", CURLFORM_END);

  curl_easy_setopt(eh->getCurlMailHandle(), CURLOPT_HTTPPOST, post);

but I'm seeing application/json being sent across the wire..

 HTTP 1.1 or later with persistent connection, pipelining supported
< HTTP/1.1 400 Bad Request
< Date: Wed, 09 Jun 2010 05:31:07 GMT
< cache-control: public,must-revalidate
< content-length: 138
< content-type: application/json

any idea?
