How to handle routes with logic to different Clusters?

What is the best way to conditionally choose a different Cluster to proxy request to?

For example, ideally I’d like to have an application with 2 Clusters (foo and bar) and a route with "clusterId": "foo" and I want to, depending on some logic applied to an incoming request, use cluster bar. Is this possible?

I’m currently using the Direct Forwarding but that means I lose out on load balancing to Clusters. I can apply any logic I need and change path/destination but without load balancing etc. Is it possible to get access to something that handles this, similar to how IHttpForwarder is used? With this method it looks like I’d need to send the request to another load-balancer for bar and let that do the load balancing.

I had a look at ITransformFactory but that looks like it is transforming requests/responses to/from a specified Cluster, rather than changing the target cluster.

Is this possible?

Triage: Interesting idea, we should find out how many more customers would use it. Moving to Backlog for now.

We added something for this called ReassignProxyRequest. See https://microsoft.github.io/reverse-proxy/articles/ab-testing.html
