Yeap! ToList was a bit overhead to get access to ForEach helper.
Aggregate helper is good, for sure because it is applicable for this case.
There is another coding life hack: calling All to process all elements of collection. 😃
But!... Ray, this file is redundant one! I left this file during rebasing just to keep the author's changes: see // TODO 😉
Both files are just container of new changes
- src/Ocelot/Requester/HttpClientBuilder.cs
- src/Ocelot/Requester/HttpClientWrapper.cs
You may check, there are no these files in develop! 🙃
This PR is not ready for reviews: it must be developed more ❗

Side note: When benchmarking this on Azure Kubernetes Service (AKS), we observed that we got a higher throughput when running with Connnection:Close than using the
Ocelot.Provider.Kubernetespackage (which queries the Kubernetes API prior to sending each request). This is one scenario where this PR is beneficial.
