CachedResponseHandler

public protocol CachedResponseHandler

A type that handles whether the data task should store the HTTP response in the cache.

  • Determines whether the HTTP response should be stored in the cache.

    The completion closure should be passed one of three possible options:

    1. The cached response provided by the server (this is the most common use case).
    2. A modified version of the cached response (you may want to modify it in some way before caching).
    3. A nil value to prevent the cached response from being stored in the cache.

    Declaration

    Swift

    func dataTask(_ task: URLSessionDataTask, willCacheResponse response: CachedURLResponse, completion: @escaping (CachedURLResponse?) -> Void)

    Parameters

    task

    The data task whose request resulted in the cached response.
    response

    The cached response to potentially store in the cache.
    completion

    The closure to execute containing cached response, a modified response, or nil.
