LB:get_current_routing()

Returns the currently allocated backend for this request.

If there is only one backend configured, this function returns the backend name in a string format. If there are multiple backends available, and they are already set via LB:routing(), then this function returns the backend name as a string. Otherwise, this returns an empty string if no backend is configured.

In case of a single routing with zero or one content routing configured, the pool name will be returned.
