[ssanders1449]

@perenesenko - Why did you close this PR? We have a sceario where argo-rollouts is controlling an ALB, but we want requests from out test clients to always go to canary pods. Is there another way to do this?

[zachaller]

@ssanders1449 this was done in #2214

[chengxiaogong]

Can you provide an example like this? There were some issues with my testing here

[Borisakov]

Is there any documentation for it?
Thanks!
