The caddy proxy will handle long lived connections, and provide metrics for requests and statuses.
The caddy proxy allows for scraping of metrics, add in the configuration to enable that scraping by prometheus.
Switch the service port to the proxy sending all traffic through it before reaching the web containers. Reduce the number of workers for web as the connection handling is now handled by the proxy.

Using caddy as a reverse proxy in a sidecar container to handle connections. This allows the proxy to hold the keep alive connections instead of the perl application. This allows the perl workers to disconnect.
Caddy provides metrics about the number of requests and the responses it is returning.
Also lowered the number of workers for the perl web server, the proxy should provide some offloading and allow for less workers, which has reduced the amount of memory the container is using.
