It's a bit of an overhead to create your own promise, angular's $http creates one for you anyway. What you're looking for is caching and http can handle it for you by passing cache:true to the service call.

So you can simply do something like this:

 module.factory("userProvider", function() {
   var getUser = function() {
   return $http.get(..., {cache:true}).then(function(data) {
       return data.user; 
   });

   return {
       getUser : getUser
   }
});
