title: Captive portal - Apple devices not getting automatic browser popup
body: <p>I have created a custom captive portal (externally hosted, made with PHP) on Ubiquity Unifi infrastructure. Everything works fine, except:</p>
  
  <p><strong>Apple devices (OSX, iOS) don't get the usual popup with the captive portal upon connection.</strong></p>
  
  <p>My employer requires this to happen. Any ideas?</p>
