title: URL Conditional config in htaccess
body: <p>My case is the following:</p>
  
  <p>I have a file named mylogic.php. This file is called from two different URLs (/url1.php &amp; /url2.php).</p>
  
  <p>What I want to archive is to add some headers to the response <em>only</em> when mylogic.php is accessed from /url1.php.</p>
  
  <p>
  
  <p>Experts: Do you have a workaround to this issue?</p>
  
  <p>THANKS in advance.</p>
