proxy to specific url failed

[terrywh]

I try to proxy a request to http://ptlogin2.qq.com/jump?ptlang=2052&clientuin=304290615&clientkey=0D399336F7C4F553C468779FC21FEC92B77EEE1F3D766C61BC3F3B19AD65E070&u1=http%3A%2F%2Fuser.qzone.qq.com%2F573692919 which actually send a "302 Found" status code, but the proxy failed to send any response which cause Chrome showing an "ERR_EMPTY_RESPONSE" error page.

i found visit that url cause proxyError, and i add some code found it to be "error: { [Error: socket hang up] code: 'ECONNRESET' }"

and i get the similar error when proxy to url http://stats.sports.qq.com/NBAImages/TeamImages/Bulls-1.png

my source code:

var http = require('http'),
    httpProxy = require('http-proxy'),
    url  = require('url');
//
// Create your proxy server
//
httpProxy.createServer(function (req, res, proxy) {
  //
  // Buffer the request so that `data` and `end` events
  // are not lost during async operation(s).
  //
  var buffer = httpProxy.buffer(req);
  var parsed_url = url.parse(req.url);
  var host = "localhost";
  var port = 8001;
  if(typeof(parsed_url.host)=='undefined') {
  } else {
      port = parsed_url.host.split(':');
      host = parsed_url.hostname;
      if(port[1]) {
        port = port[1];
      }else{
        port = 80;
      }
  }
  //setTimeout(function () {
    proxy.proxyRequest(req, res, {
       'host': host,
       'port': port,
       'buffer': buffer,
    });      
  //}, 2000);
}).listen(8000);

The server you're trying to proxy to might be expecting certain headers that aren't being passed through - or it might be rejecting requests that have obviously been proxied.

node-http-proxy sets the x-forwarded-* headers, and your connections may be getting refused because of this.

@wuhaocn2008 are you still having an issue with this?

[terrywh]

it seems the latter url is ok right now, but the first url is still having some kind of issue when i use the proxy server on CHROME to visit. It keeps loading for a very long time.

I think the problem is the query part of the URL. I'm going to work on getting rid of the hanging problems in node-http-proxy, I think that's the source of a lot of people's problems. Clear error messages are far more useful than hanging.

[coderarity]

It sounds like it was hanging - I just added a pull request to give reasonable errors instead of just hanging. See nodejitsu/node-http-proxy#216. After that pull request is merged in and a new version is up on npm, can you try it again and tell me what error it gives you (if any)?

[terrywh]

USE proxyError to track the errors, here is what i got when proxy the first url:

{ [Error: socket hang up] code: 'ECONNRESET' }

it seems you are right about the x-forwarded-for thing. when i proxy some url, it will emit that reset error. For the specific url on top, the reason might be that there should not be a header "x-forwarded" or the server will close the connection.

Thank you for all your trouble.
