Using HAproxy as frontend proxy

Help
1

I use haproxy as a frontend of my website, and would like to serve writefreely out through it.

There are other services, so my plan was to put writefreely under e.g. https://example.com/blog and configure an haproxy frontend/backend to proxy that

frontend front_https
...
        acl writefreely_uri path_beg /blog
        use_backend backend_server if writefreely_uri

backend backend_server
        server             writefreely 127.0.0.1:8083

This isn’t working. I could go through nginx proxying also or instead, but that’s messier.

Wondering if anyone has done this?
