File Upload & Post problem - libcurl + PHP

Hi,

 I am using libcurl + PHP to upload a file and also post some parameters to a website after successful login.
The file to be uploaded and the parameters to be posted is set in an array and the array is posted to the website.
Cookie- handling is also taken care of in the code
 libcurl version used : curl 7.15.3 (i586-pc-mingw32msvc) libcurl/7.15.3 OpenSSL/0.9.7c zlib/1.2.2
php version used:php-5.1.2

Problem : Upload & post to the website is not happening and i am getting directed to the error page with trace summary as below
 Expect: 100-continue
Content-Type: multipart/form-data; boundary=----------------------------0b038ba78c65
 < HTTP/1.1 100 Continue
< HTTP/1.1 200 OK

 Could anyone tell why this problem occurs?
Please find my code and output trace below.
 Thanks,
LP
