I should think that in such cases, the end client is exactly not what
you want to be choosing which server it gets redirected to. You'd
be wanting to base that on policies defined at the pooler. There are
already plenty of client-supplied attributes you could use as inputs
for such policies (user name and application name, for instance).
Why do we need to incur a protocol break to add another one?
