How to rewrite a path to a backend service dropping the prefix and passing the remaining path?

when HTTP_REQUEST {
 set uri [HTTP::uri]
 if { $uri contains "anything" } {
     HTTP::uri "/[join [lrange [split $uri "/"] 2 end] "/"]"
 }
}

That seems to match the syntax on the ingress example. A quick search on stack seems to also support the same syntax. Are you on at least ingress controller 2.0 and kubernetes 1.22? the referenced API version doesn't seem to be compatible earlier.

Hello xuwen & JRahm,

Thank you fo your quick responses and help.  After a break, I adjusted the path, as below, and was able to successfully route to httpbin and preserve the path after the prefix.  Hopefully, this will help others... 🙂

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: mikie-ingress
  namespace: mikie
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
  ingressClassName: nginx
  rules:
    - host: abczzz.com
      http:
        paths:
          - backend:
              service:
                name: httpbin-service
                port:
                  number: 8999
            path: /httpbin/(.*)
            pathType: Prefix

So, I started from scratch at Digital Ocean... I created two Kubernetes clusters using their default configuration:
  * aboh-cluster is the community version of nginx ingnress
 * abitofhelp-cluster is the commercial version of nginix ingress

Nginx community: helm 4.1.3, ingress-nginx 1.21, nginx 1.19.10
Nginx commercial: helm 2.2.2, ingress 1.22

Unfortunately, the outcome is the same as in my previous test.  The community version works with the deployment/service and ingress manifests.  The commercial version with 404 errors using the same manifests and curl commands.  

I have captured the following in the attached compressed file:

* Descriptions of the services and ingresses;
* Manifests for the deployments, services, and ingresses;
* Logs capturing the curl command and the result 

I am not sure where to go from here...  We want to use the commercial version with support, but cannot seem to get it to work.  

Thanks for any hints or help, 

Mike

Since haproxy is based upon nginx, I set up the same environment and test in a new cluster at Digital Ocean.  Unfortunately, the tests failed as with the commercial version.  Attached is an updated compressed file including the haproxy work.
