Problem

Does node-http-proxy support HTTP CONNECT requests, like: [code block] The proxy would then maintain the two connections, and forward the SSL traffic between the client and the target server. If so, how do I set this up? Thanks

Enable HTTP CONNECT Support in Node-HTTP-Proxy

Medium Risk

Node-http-proxy does not natively support HTTP CONNECT requests for tunneling SSL traffic. This is because it primarily focuses on HTTP/HTTPS request forwarding without handling the specific requirements of establishing a tunnel for SSL connections. To enable this functionality, additional configuration is needed to handle the CONNECT method properly.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Install Node-HTTP-Proxy

    Ensure that node-http-proxy is installed in your project. If it's not installed, you can add it using npm.

    bash
    npm install http-proxy
  2. 2

    Set Up Basic Proxy Server

    Create a basic proxy server using node-http-proxy. This server will listen for incoming requests and handle HTTP CONNECT requests specifically.

    javascript
    const http = require('http');
const httpProxy = require('http-proxy');

const proxy = httpProxy.createProxyServer({});

const server = http.createServer((req, res) => {
  if (req.method === 'CONNECT') {
    // Handle CONNECT requests
    proxy.ws(req, res, { target: req.url });
  } else {
    // Handle regular HTTP requests
    proxy.web(req, res, { target: 'http://your-target-server.com' });
  }
});

server.on('upgrade', (req, socket, head) => {
  proxy.ws(req, socket, head);
});

server.listen(3000);
  3. 3

    Configure Target Server

    Replace 'http://your-target-server.com' in the code above with the actual target server you want to connect to. Ensure that the target server supports SSL connections.

  4. 4

    Test the Proxy Server

    Use a tool like curl or Postman to send a CONNECT request through your proxy server to verify that SSL traffic is being tunneled correctly.

    bash
    curl -x http://localhost:3000 -k https://your-secure-server.com

Validation

Check the response from the target server after sending a CONNECT request. If the connection is established successfully, you should see no errors, and the SSL traffic should be tunneled correctly. Additionally, monitor the server logs for any errors during the connection process.
