First of all, thank you for your reply.

I am using HTTPS to call POST.
I am running my application on 64bit Linux Red hat distribution
4.1.2-46 and here is what I got from rpm -qa.

curl-devel-7.15.5-2.1.el5_3.5
curl-7.15.5-2.1.el5_3.5

Please let me know if I am missing anything or if I need to give your
more information.
Thank you.
