Description

How it could work:

  • Allow customization of DNS resolution (see also #92) which may return multiple addresses per host
  • Allow overriding of target addresses when creating a connection
  • In the pool, use different target addresses per slot
  • Maybe a custom scheduling is also needed so that sequential requests don't all go the same then-idle connection

One way that users could hack in the first parts without changes to akka-http would be to use a custom ClientTransport returning a Flow that would transparently connect to different addresses each time it is materialized.
