title: How to have a custom URL for an icon on the iOS home screen
body: <p>Is it possible to make a custom URL for an icon on the iOS home screen?
  Or at least have a way for the user to edit the URL themselves?</p>
  
  <p>UPDATE: To be more specific, here's what the client said:</p>
  
  <p>"Because of our use of authentication, the URL of the landing page that [website] takes you to changes to a long URL with a session ID.  Right now, when I use the Add to Home Screen function, it associates the icon with the long URL which, because of the session ID, won't work after a couple of days.  Is there any way to change the URL to [website] (our stable and persistent URL) after or before the Add to home screen function is invoked"</p>
  
  <p>Also, the website isn't a web app, so I'm not sure if web app things would apply here.....?</p>
