Get the HTTPURLResponse from a Siesta Response

Question

I'm fighting against REST API that performs a 304 redirect; what I need is to take the destination URL of the redirect and open it with the browser (I know, it's a little of a perversion). I successfully intercepted the redirect, thanks to this nice lad reversepanda: https://github.com/bustoutsolutions/siesta/issues/210 but still I didn't figure out how to take the redirect url in the callback of the GET request (success or failure)

resource.load().onSuccess{ response in
        //HERE I WOULD LIKE TO TAKE THE URL OF THE REDIRECT 
        //(if I print the response I can see the HTML of the destination web page where the user should land)
    }.onFailure{ error in
        //using 'completionHandler(nil)' in the 'willPerformHTTPRedirection' method of the delegate, brings me here
    }

Any suggestion on how I could resolve this problem?

Thank you!

Take a look inside RequestChain.swift, it has some comments with example which can help. I believe you can do something like:

func redirectRequest() -> Request {
  return self.yourAnotherRequest(onSuccess: {
    }, onFailure: { error in
  })
}

func yourRequest(request: Siesta.Request) -> Request {
  return request.chained {
    guard case .failure(let error) = $0.response,
        error.httpStatusCode == 401 else {
            return .useThisResponse
    }

    return .passTo(
        self.redirectRequest().chained {
            if case .failure = $0.response {
                return .useThisResponse
            } else {
                return .passTo(request.repeated())
            }
        }
    )
  }
}

You can search more examples with keywords chained, useThisResponse and passTo in Siesta sources.
