it looks like upstream haproxy support something like this:
https://www.haproxy.com/de/blog/accelerate-your-apis-by-using-the-haproxy-cache/
https://haproxy-ingress.github.io/docs/configuration/keys/

I  opened a slack thread to check if there is any possibility but it looks currently OCP ingress doesn't support cache as  confirmed by  Andrew McDermott
