Angularjs keep $http result cached

Question

Good people, next, I’m putting together an application that involves a lot of navigation and data visualization. It would go something like this:

There is a customer table (+500 registered) with approx. 35 columns of informative data per customer. In addition, there is the view of processes, service orders, etc. All of them are generated based on clients.

The system usage flow involves a lot of navigation enters these views. For example:

Access clients -> select one of them -> view their service orders -> go back to customers -> view another client -> If you enter new order, access the service order view, etc...

For each of these views I make one $http where I take a list of customers, a list of processes, or a list of service orders, depending on the view.

The request is done with a simple code, through a Factory

//factory
getCliente: function() {
    return $http.get("api/func.php?action=get_cliente").then( 
        function(res) { return res.data;},
        function(err) {alert(feedbackError);}
    );
},

//controller
factCliente.getCliente().then(function(res) {
    $scope.detcliente = res;
});

These lists may change, or receive new data, but the frequency with which this happens is much lower than the frequency with which the user needs to navigate.

The problem

The application is starting to get slow at the time of displaying the views. Around 1-2s delay (because depending on the view, involves a combination of sql to get the list - In this area, we have no more way to move).

We cannot generate the list and save to a file .json (as we did before) because some data is confidential, so only the logged in user can view.

Doubt

What could be done to solve this problem? I am currently using a limitTo:50 that helps a little, but it has some limitations, for example: If the table displays only 10 records and the user tries to filter it through a text field, the other results will not appear on the screen (at least not as is for now).

Is there any way to keep the data cached in Angularjs to facilitate performance with the use of $http?
