Please have a look at lib/README.encoding in the Curl source tree.
Setting Accept-Encoding by using CURLOPT_ENCODING is a polite request to
the server to send a compressed response, if it can.

If you want the client to send compressed data to the server, you'll
need to compress the data yourself and add the compressed content to the
post request. The server will have to know how to figure out that
you're sending it compressed data.

Curl has two different POST interfaces. The first is described here:

http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTPOST

The second used curl_formadd:

http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTHTTPPOST
http://curl.haxx.se/libcurl/c/curl_formadd.html
