 An intercept will _intercept_ the request when an error of type `ResponseError` occurs.
 
-When this happens `intercept(_:retry:)` will be triggered and you should return `true` or `false` to indicate if you want the normal response flow to stop. When you stop the flow it will be possible to retry the request by calling the `retry()` block.
