 * Helper to execute an HTTP POST request
 * Source: http://netevil.org/blog/2006/nov/http-post-from-php-without-curl
 *         originaly named after do_post_request
 * Does not require cUrl but requires openssl for performing https POSTs.
 *
 * @param string $sUrl The URL to POST the data to
 * @param string $sData The raw data to POST
 * @param string $sOptionnalHeaders Additional HTTP headers as a string with newlines between headers
 * @param hash	$aResponseHeaders An array to be filled with reponse headers: WARNING: the actual content of the array depends on the library used: cURL or fopen, test with both !! See: http://fr.php.net/manual/en/function.curl-getinfo.php
 * @param hash $aCurlOptions An (optional) array of options to pass to curl_init. The format is 'option_code' => 'value'. These values have precedence over the default ones
 * @return string The result of the POST request
 * @throws Exception
