<div class="block">Supplies Authorization information to an HTTPConduit.
<p>
A HTTPConduit keeps a reference to this HttpAuthSupplier for the life
of the HTTPConduit, unless changed out by dynamic configuration.
Therefore, an implementation of this HttpAuthSupplier may maintain
state for subsequent calls.
<p>
For instance, an implementation may not provide a Authorization preemptively for
a particular URL and decide to get the realm information from
a 401 response in which the HTTPConduit will call getAuthorization for
that URL. Then this implementation may provide the Authorization for this
particular URL preemptively for subsequent calls to getAuthorization.</div>
