多个readStreams管道请求

Question

是否可以一次性将多个图像发送到远程服务器，或者我是否可以单独发出请求？

var http = require('http');
var request = http.request(options, function(response) {

}

var readStream = fs.ReadStream(images[0]);
readStream.on('error', reject);
readStream.on('close', function(){request.end()});
readStream.pipe(request);
