Hi Linus,
Thanks for the reply, but my problem stays put.
By including the VERBOSE option also I am not getting anything different... The following is the respose and it does not give any clues what is going wrong.

HTTP/1.1 412 Precondition Failed

First of all, you should try the CURLOPT_VERBOSE option to see what is
going on.

    curl_setopt($ch, CURLOPT_VERBOSE, TRUE);

Secondly, you don't need to supply the Content-Length header, since that
is calculated and added by libcurl.
