title: Retrieving original destination from iptables after REDIRECT
body: <p>I'm writing an application proxy for generic use.</p>
  
  <p>I want to use this as a transparent proxy, where my original plan is to use iptables with a REDIRECT rule forward all connections to my application proxy.</p>
  
  <p>The problem here is of course, that my application proxy lose the information about the intended destination.</p>
  
  <p>Is it possible to query iptables to retrieve the originally intended recipient?
  Any other possible solution to this problem is also appreciated!</p>
