Haproxy configuration to share a port 80/443 with nginx (or Apache, etc) and SSH

cmd to ssh trough nginx

ssh foo.example.com -p 80

haproxy.cfg

global
    log         127.0.0.1 local2

    chroot      /var/lib/haproxy
    pidfile     /var/run/haproxy.pid
    maxconn     4000
    user        haproxy
    group       haproxy
    daemon

    # turn on stats unix socket
    stats socket /var/lib/haproxy/stats

defaults
    timeout connect 5000
    timeout client  50000
    timeout server  50000

frontend main
    mode tcp
    bind 0.0.0.0:80
    tcp-request inspect-delay 5s
    #find ssh signature
    use_backend ssh             if  { payload(0,7) -m bin 5353482d322e30 }
    default_backend webserver

backend ssh
    mode tcp
    timeout server 2h
    timeout client 2h
    server ssh-localhost 127.0.0.1:22

backend webserver
    mode tcp
    server webserver-localhost 127.0.0.1:8080

nginx.conf

server {
    listen 127.0.0.1:8080;
....
}

Should also work with TLS/SSL, juste need to use tcp backend to a nginx/apache serving the certificate.
