Which part do you need help with? The HTTP protocol for use on the clientside, or how to setup something on the serverside (php,asp,etc) to recieve it?

I was faced with a similar problem lately and solved it by using libcurl for the HTTP transfer. The library is really nice and quite easy to use.
Here it an example that POSTs some data:

CURL * Curl = curl_easy_init();
if (Curl)
{
curl_easy_setopt(Curl, CURLOPT_URL, "http://www.yoursite.com/");
curl_easy_setopt(Curl, CURLOPT_POST, TRUE);
curl_easy_setopt(Curl, CURLOPT_POSTFIELDS, &Postdata);
curl_easy_setopt(Curl, CURLOPT_POSTFIELDSIZE, sizeof(Postdata));

curl_easy_perform(Curl);
curl_easy_cleanup(Curl);
}


You can also set some callbacks to keep track of the transfer progress. Just take a look at the documentation.

I haven't dealt with the receiving side so far but it should be no problem to read the POST data on the server-side and write it into a file.
