ffinity to a particular destination host may be
lost when one or more hosts are added/removed from the destination
service.</p>
<p>Note: consistent hashing is less reliable at maintaining affinity than common
&ldquo;sticky sessions&rdquo; implementations, which often encode a specific destination in
a cookie, ensuring affinity is maintained as long as the backend remains.
With consistent hash, the guarantees are weaker; any host addition or removal can
break affinity for <code>1/backends</code> requests.</p
