title: Set Property Value on Master Page from Content Page
body: <p>I need to pass data to a variable in my master page each time a page is loaded.</p>
  
  <p>I have a string[] of RequiredRoles that I set on each content page defining what roles are required to access that page.</p>
  
  <p>On my master page, I have a method that takes this array, and checks to see if the current user is in one or more of those roles.</p>
  
  <p>How would I go about managing this? I basically want each page to have a String[] RequiredRoles defined, and the master page will load this on each call and check to see if the users are in those roles.</p>
