在配置块中设置$ httpProvider.defaults.cache

Question

How can I set $httpProvider.defaults.cache in config block in my application? Whenever I tried I was receiving "ReferenceError: $cacheFactory is not defined" error.

So now, I am trying to find out alternative methods to get this done.

Hence please advice what are the workarounds to achieve this.

If you read this section on $http caching , it says:

You can change the default cache to a new object (built with $cacheFactory) by updating the $http.defaults.cache property. All requests who set their cache property to true will now use this cache object.

Notice how you can do it with $http instead of $httpProvider . The trick is to not set the default cache in config, but rather in a run block, or some other service/factory you have created. For example:

app.run(function($http, $cacheFactory){
    $http.defaults.cache = $cacheFactory('myCache', { capacity: 50 });
});

After reading the docs again, I realised I misread them originally. If you read the docs carefully for the default, it reads:

defaults.cache - {Object} - an object built with $cacheFactory

This is poorly written, but I think that it means that you pass in the object that you would use to create a cache using $cacheFactory . For example:

$httpProvider.defaults.cache = { /* your cache config here */ };

I believe the provider will utilise $cacheFactory behind the scenes rather than you calling it explicitly.
