SSH tunnel through an HTTP CONNECT proxy
========================================

Download and run:
  curl -fsSLO https://filesv.vnstech.cloud/install-ssh-http-proxy.sh
  chmod +x install-ssh-http-proxy.sh
  ./install-ssh-http-proxy.sh

The installer works on Linux and macOS. It asks for:
  - SSH server host, port and username
  - HTTP proxy host and port
  - Optional HTTP Basic proxy username and password
  - Optional SSH private key path

After installation:
  ssh customer-jump

Create a SOCKS5 tunnel:
  ssh -N -D 127.0.0.1:1080 customer-jump

Create a local port forward:
  ssh -N -L 127.0.0.1:8080:internal-host:80 customer-jump

Notes:
  - The HTTP proxy must allow the CONNECT method to the SSH server and port.
  - Proxy credentials are stored locally with permission 600.
  - SSH config is stored in ~/.ssh/config.
