Avoid refreshing the page upon pressing the back button in AngularJS

Currently, I am working on building a web application that heavily relies on AJAX with AngularJS. One issue I am facing is that when the user clicks the back button on their browser, the requests are being re-made which results in data having to be reloaded. This can be frustrating, especially for data that takes 2-3 seconds to load. I am wondering if there is a solution to prevent this from happening, or perhaps a different approach to designing my application so that the data persists throughout a session. Any suggestions would be greatly appreciated.

If you are utilizing ngResource to fetch data from an API, make sure to enable caching by setting it to true in the actions section as outlined in the documentation.

cache – {boolean|Cache} – When set to true, a default $http cache is utilized to store the GET request. Alternatively, if a cache instance is created using $cacheFactory, that specific cache will be used for storage.

Visit AngularJS ngResource Documentation

For example:

this.service=$resource('www.example.com/api/v/stats',
        {
            callback: "JSON_CALLBACK"
        }, {'foo': {'method': 'GET', 'cache': true}}
    );

By fetching data through this.service.foo(), the request will be cached and when navigating back using the browser's back button, the cached data will be loaded instead of making another request to the server.

Currently, in the development of my app, I heavily rely on the $routeProvider for managing each module. Here's a snippet of what I typically do:

$routeProvider.when(/someModule/page1Condition1, {templateUrl: 'page1.tpl.html', controller: 'page1Ctrl'});
$routeProvider.when(/someModule/page1Condition2, {templateUrl: 'page1.tpl.html', controller: 'page1Ctrl'});

Subsequently, in the controller for page1, I implement something along the lines of:

if($location.path()==='/someModule/page1Condition2){
    // Perform specific actions when Condition2 is true
    // Such as fetching data using AJAX
    $http.get('somePath')
        .success(function(data){
            $scope.myData = angular.fromJson(data);
        });
}

This approach allows me to utilize just one controller while selectively retrieving data based on the URL path. It aims to mimic RESTful behavior, albeit not complying with full REST principles.

It's worth noting that my client has imposed some unconventional requirements, indicating that this solution may not be optimal (potentially serving as an antipattern or merely a temporary workaround).
