title: Apache force DNS lookups
body: <p>I've got an Apache that's proxying requests to an external entity:</p>
  
  <pre><code>    ProxyPass /something  https://external.example.com/somethingelse
  </code></pre>
  
  <p>This external site likes to switch the values of that domain based on where they want their traffic. Apache seemingly doesn't pick up the new value until it's restarted. Is there a way to force Apache to do new lookups based on certain amount of time? After some research and even looking at the code, I don't see an obvious answer. If that isn't an option, any other suggestions? </p>
