Why not use CURLOPT_HTTPPOST then? Helps you with all the tricky details...
See http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTHTTPPOST

Also, that content-type looks wrong. It is supposed to include the boundary
string too there.

This isn't necessary really. Unless you're talking to some really ancient
server.

This is a broken server. It is often the Expect: header that confuses stupid
servers...
