Unable to Configure Load Balancing Per Request Over Persistent Connection

I have a simple goal: I’d like to load balance a couple servers using the uri hash balance algorithm and I’d like to support persistent connections to haproxy with load balancing for each request. Unfortunately, I haven’t been able to achieve this behavior. I’ve tried a variety of configurations, namely option http-keep-alive, but nothing is working. The configuration file is below.

The behavior I’m witnessing is the hash is used on the first request to bind to a server for the duration of the persistent client connection. I was able to achieve load balancing per request with option httpclose, but that prevents persistent client connections. Is there a way to have persistent client and server connections with load balancing on each request?

In summary, I see tunnel behavior and not keep-alive behavior.

I using HA-Proxy version 1.8.14-52e4d43 2018/09/20

global
    daemon

frontend http-in
    mode http
    timeout client 60s
    bind *:8080
    default_backend servers

backend servers
    mode http
    timeout connect 5s
    timeout server 60s
    balance uri
    option httpchk GET /health
    http-check expect status 200
    server server1 <ip>:<port> check
    server server2 <ip>:<port> check
