title: Apache webserver - What happens to requests, when all worker threads are busy
body: <p>As far as I researched, the scenario when all worker threads are busy serving requests, what happens to the requests that comes next.</p>
  
  <ol>
  <li>Do they wait?</li>
  <li>Is this related to some configurable parameters?</li>
  <li>Can I get the count of such requests ?</li>
  </ol>
  
  <p>Adding to this please can you explain or give a link where I can get a clear picture of request processing strategy of Apache webserver?</p>
  
  <p>Thanks for Looking at!!</p>
