How do I configure Tomcat HAProxy to forward from localhost:8080/path to 1.2.3.4:8080/path?

Question

All the HAProxy tutorials give examples only about port 80 and some default path. How do I configure Tomcat HAProxy to forward from localhost:8080/path to 1.2.3.4:8080/path? I can't figure it out in the config file

Answer 1

Assuming you want to proxy all requests coming to /path to 1.2.3.4:8080/path, you could do something like this:

frontend http_fe
    bind *:443
    option forwardfor
    use_backend be_path if { path_beg /path }
    default_backend default_be

backend be_default
    ...

backend be_path
    mode http 
    option forwardfor
    server srv01 1.2.3.4:8080
