Cache specific request, not whole service.

I think that is really a common situation, when you need to cache result of a specific request that ideological belongs to some HttpService. But now all requests that belong to the service with cache hook are caching.

For example, I have a service that provides auth methods and caching ableProfile request is a good idea, but caching isLogined request looks pretty weird. I really don't want to create HttpService for each request I need to cache.

Do you plan implement that sort of functionality or did I miss something and there is some elegant way to do it?

For the time being, I would introduce the following (empty) protocol:

protocol CachableJsonRequest: JsonRequest { }

Then, in your hook, you could implement the onSchedule and onSuccess methods and dynamically check for the type of the request, i.e.:

guard request is CachableJsonRequest else {
    return nil
}

I know this is not ideal (as it also requires you to implement your own CachingServiceHook) -- let me know if you got any ideas.
