I have a service using Azure Kubernetes cluster and AKS load balancer. I want to forward some HTTP(client) requests to all instances. is there any way to configure this behavior using AKS or Kubernetes in general?
Say I have XYZ API running two replicas/instances.
I have some rest API requests to the app domain.com/testendpoint
Currently, using AKS load balancer it sends the requests in a round-robin fashion to XYZ-1 and XYZ-2. I am looking to see if it is possible to forward a request to both instances (XYZ-1 and XYZ-2) when the request endpoint is testendpoint
and all other API requests use the same round-robin order.
The use case to refresh a service in-memory data via a rest call once a day or twice and the rest call will be triggered by another service when needed. so want to make sure all pod instances update/refresh in-memory data by an HTTP request.

This is not a feature in the HTTP protocol, so you need a purpose built service to handle this.

I suggest that you create a new utility service, "update-service" - that you send the call once a day to. This service then makes a request to every instance of XYZ, like XYZ-1
and XYZ-2
