title: How to manage persistant caching in Office 365 for Windows and Mac OS?
body: <p>I am new in Office 365 Add-ins. I want to know about caching. I am working on a Add-In using Office.js. I want to manage caching.</p>
  
  <p>Scienario:</p>
  
  <p>1- Add-In will get data from server once in a day. Data can be in MBs(i.e 5 MB).</p>
  
  <p>2- It should store somewhere. So, user can use it even there is no internet connection. </p>
  
  <p>Is there any internal caching mechanism provide by Office APIs?</p>
  
  <p>I was also thinking to store in File. Is it possible to create and manage File using Office Add-ins in Windows and Mac?(I am just curious about File permission in Mac)</p>
  
  <p>Please suggest</p>
