title: WCF request response lifecycle
body: <p>I am new to WCF and trying to understand a few things. </p>
  
  <ol>
  <li><p>Is every request/response handled in separate mutex threads/process host? Can same thread/process handle multiple requests? Is there any request queuing involved? </p></li>
  <li><p>If I have global/static variables is their scope limited to the given request response sequence?</p></li>
  </ol>
  
  <p>Thanks in advance.</p>
