title: Sharing storage between instances of same web app
body: <p>I built a web application that i have running on multiple raspberry pis, I wanted to add storage that is shared by all the web app instances. Basically what I want to achieve is for each instance I open in my browser it saves the device name and URL to my browser (Local storage is what I went with but it's not shared) the web app would then open the storage read all previously accessed pis for easy switching.</p>
  
  <p>I tried to do this using local storage but didn't work as apparently it's per instance and not shared. anyone can suggest a proper way to achieve this ?</p>
