should help you out Turns out, if one wants to proxy websockets through an https proxy, one should make the proxy part normal websockets (ws://) not secure web sockets (wss://) which makes sense as the https proxy would have handled the ssl portion already and there is nothing to do.
ProxyPass /websockify ws:// retry=3
ProxyPassReverse /websockify ws:// retry=3

Can reverse proxy rules affect apache reverse proxy performance?

Tag : performance , By : user147496

fixed the issue. Will look into that further To get accurate numbers one would have to benchmark this, and preferably with your architecture, software versions, and server. However think of it like this:
One ProxyPass rule causes one string comparison, probaby by using PCRE. All ProxyPassReverse rules cause string comparison (and potentially search & replace) against 5 header fields. Your production server can probably handle some 5+ million ProxyPass and 1+ million ProxyPassReverse operations per second.
ProxyPass        /website/test/            http://www.example:8080/web/test
ProxyPass        /website/test2/           http://www.example:8080/web/test2
ProxyPassReverse /website/                 http://www.example:8080/web

VNC server -> websockify -> noVNC issue

hope this fix your issue Did you follow this guide? https://github.com/kanaka/websockify/wiki/Compiling-Websockify-as-Windows-Executable
Websockify uses the python multiprocessing module. This module is problematic on Windows, especially with older versions of python. You might try python 3.2 or greater and see if you have more success although no guarantees. Websockify is developed and tested on Linux only.

Reverse proxy from NodeJS to Apache using node-http-proxy does not work

it helps some times Apparently replacing with localhost in the hello.js script did the trick. Not completely sure why (I guess it has something to do with my hosts file), but it works.

Node Http Proxy - basic reverse proxy doesn't work (404s)

it fixes the issue I'm trying to get a very simple proxy working with node-http-proxy which I would expect to just return the contents of google: , You need to set the Host header of your request
const http = require('http');
const httpProxy = require('http-proxy');

const targetHost = 'www.google.co.uk';

const proxy = httpProxy.createProxyServer({
    target: 'http://' + targetHost

http.createServer(function (req, res) {
    proxy.web(req, res);


proxy.on('proxyReq', function(proxyReq, req, res, options) {
    proxyReq.setHeader('Host', targetHost);
const proxy = require('express-http-proxy');
app.use('*', proxy('www.google.co.uk', {
  forwardPath: function(req, res) {
    return url.parse(req.originalUrl).path;

Nginx - Reverse proxy to an already reverse proxied location or double reverse proxy?

To fix this issue The application being loaded is set up to load assets from the server root, not with server root + /node2/
