Problems with simple reverse proxy

[AndersML]

Hi, I want to do something similar to
https://support.rstudio.com/hc/en-us/articles/200552326-Running-RStudio-Server-with-a-Proxy

but with node-http-proxy.

var http = require('http'),
    httpProxy = require('http-proxy');


var proxy = new httpProxy.createProxyServer({
  target: {
    host: '10.10.10.10',  // fake ip of cause
    port: 8787,
    hostRewrite: true,
    autoRewrite: true,
    protocolRewrite: true,
    httpVersion: '1.0'
  }
});

var proxyServer = http.createServer(function (req, res) {
  proxy.web(req, res);
});

// Listen to the `upgrade` event and proxy the
proxyServer.on('upgrade', function (req, socket, head) {
  proxy.ws(req, socket, head);
});

proxyServer.listen(80);

This almost work, but I get a error when signing into the Rstudio server. It works fine using the nginx proxy from the link above. Does anybody known what I am doing wrong?

I have used node-http-proxy for other project without problem, an I really like the versatility of the system!

I'm not sure if this is your problem or not, but I'm pretty sure protocolRewrite should be set to either 'http' or 'https'.

@AndersML have you been able to resolve this issue?

@AndersML I'm encountering exactly the same issue with Rstudio server. Have you found a fix?

I was not able to resolve it. I changed proxy to nginx instead, where I used some Lua code to do the special logic I needed
