Hi all,
i' ve got a question regarding the marking of a Varnish backend as sick.

Let's assume that my backend server is healthy an I manually set that
particular backend as sick what will happen to existing open connections?

To be more specific is the sick operation same like Haproxy's drain
i.e. Is it a  graceful operation ?
