Is there a way to automatically retry a request given a specific response (for example, HTTP 421) with HttpClient ?

Using the okhttp client you can intercept the response, check the code. If code == 421. Make request again.

I've had a look at interceptors for HttpClient :

requestPipeline

and

responsePipeline

. The problem is, which phase should I intercept ? How to re-issue a request with the same pipeline as the original ? It seems that when calling

httpClient.execute(...)

, it loses the ability to deserialize Json.
