 * Hi. This URL is used in order to load your preferences for how OneSignal should
   function on your website.
 * It has a 5-minute browser cache because we want to make sure that any changes
   people make to their settings don’t take longer than 5 minutes to take effect
   for their visitors.
 * GTMetrix appears to be incorrectly identifying this as a static file, but it’s
   actually a dynamic one with a short cache duration. Hope that helps!
