If you are actually looking to buffer the full request you can do something
like following:
function callServer(req, res) {
var body = '' ;
var options = { host: 'localhost', port: 3000, path: req.url } ;
var callback = function(response) {
var chunks = [];
response.on('data', function (chunk) {
chunks.push(chunk);
});
response.on('end', function () {
res.writeHead(response.statusCode,
response.headers) ;
res.end(Buffer.concat(chunks)) ;
});
} ;
http.request(options, callback).end();
}
In your example it is the += that is converting to a string that messes up
the result. Some buffer bytes get expanded out to multiple utf bytes when
you do that.
