How to tell OkHttpClient to ignore cache and force refresh from server?

Question

In my android application, I am using Retrofit with OkHttpClient with caching enabled to access some APIs. Some of our APIs sometimes return empty data. We provide a "Refresh" button in the app for the client to reload data from a specific API.

How do I tell OkHttpClient that a specific request should ignore the cached entry. Alternatively, is there a mechanism to delete the cached response corresponding to a single request?

I see Cache.remove(request) method but it is marked as private.

As Jake Wharton suggested in issues, do this to ignore the cache:

request.setCacheControl(CacheControl.FORCE_NETWORK);

I was using an older version, updated to 3.4 and your solution working. Thanks inder – Nidhin Aug 10 '16 at 08:18

is it able to set the cacheControl from OkHttpClient class, not from the Request class? – zihadrizkyef Mar 14 '17 at 16:34

Yes - to disable caching globally, create the client with a null cache: `new OkHttpClient().newBuilder().cache(null).build();` – Simon Apr 28 '17 at 12:19

Is it possible to annotate some API calls to not use the cache at all ? – Someone Somewhere Sep 22 '17 at 09:08
This does not work if you use the Coroutines Adapter. Any Ideas ? – Till Krempel Jan 24 '19 at 14:14

@Headers("Cache-Control: no-cache")

on the method should work. If you want to do it dynamically you can add a

@Header("Cache-Control")

String cacheControl parameter and pass null or "no-cache"
