Update reverse proxy middleware targets?

[danthegoodman1]

Using the middleware.Proxy(middleware.NewRoundRobinBalancer(targets)), is there a way to update the targets while the server is running? So for example if new upstream targets joined, or healthchecks failed on one of them.

Ah of course 5 seconds after I ask the question I find this:

rrb := middleware.NewRoundRobinBalancer(targets)
Server.Use(middleware.Proxy(rrb))

rrb has AddTarget and RemoveTarget methods :)
