	      // create both cURL resources
	      $ch1 = curl_init();
	      $ch2 = curl_init();

	      // set URL and other appropriate options

	      //create the multiple cURL handle
	      $mh = curl_multi_init();

	      curl_multi_add_handle($mh,$ch2);

	      $active = null;
	      //execute the handles
	      do {
		  $mrc = curl_multi_exec($mh, $active);
	      } while ($mrc == CURLM_CALL_MULTI_PERFORM);

		      } while ($mrc == CURLM_CALL_MULTI_PERFORM);
		  }
