AngularJS: Call a particular function before any partial page controllers

Question

I want to call a particular function: GetSession() at the beginning of my application load. This function makes a $http call and get a session token: <

You have not provided any details related to GetSession. For scenarios like this you should use the resolve property while defining your routes in $routeProvider. I see you are using resolve already.

What you can do now is to wrap the GlobalSessionToken into a Angular service like GlobalSessionTokenServiceand call it in the resolve to get the token before the route loads. Like

resolve: { 
            loadData: function($q){ 
                return LoadData2($q,'home'); 
            },
            GlobalSessionToken: function(GlobalSessionTokenService) {
                 return GlobalSessionTokenService.getToken()  //This should return promise
            }
         } 

This can then be injected in your controller with

controllers.MasterController = function($rootScope, $http,GlobalSessionToken){
