title: Retrofit - Intercept responses globally
body: <p>I'd like to intercept all responses received by the retrofit engine, and scan for HTTP error code, for example error 403.</p>
  
  <p>I'm aware I can use the failure(RetrofitError error) callback of every request and check for 403's but I'd like to wrap the response globally.</p>
  
  <p>I can see that request interception is possible, but I do not see a similar option for response.</p>
  
  <p>Any suggestions?</p>
