title: How to use an Exponential Backoff strategy with Apache httpclient?
body: <p>The <a href="https://hc.apache.org/httpcomponents-client-dev/httpclient-cache/apidocs/org/apache/http/impl/client/cache/ExponentialBackOffSchedulingStrategy.html" rel="noreferrer">docs</a> specify a class of ExponentialBackOffSchedulingStrategy but it doesn't seem to exist in version 4.5.</p>
  
  <p>Also, didn't find anything that explains HOW to use it.</p>
  
  <p>Anyone used something like this before?</p>
