 * Fix: Drop `Content-Length` header when redirected from POST to GET.
 * Fix: Correctly read cached header entries with malformed header names.
 * Fix: Do not directly support any authentication schemes other than "Basic".
 * Fix: Respect read timeouts on recycled connections.
 * Fix: Transmit multiple cookie values as a single header with delimiter.
 * Fix: Ensure `null` is never returned from a connection's `getHeaderFields()`.

 * As policy, implementations of this interface are responsible for selecting which cookies to
 * accept and which to reject. A reasonable policy is to reject all cookies, though that may
 * interfere with session-based authentication schemes that require cookies.
 *
 * As persistence, implementations of this interface must also provide storage of cookies. Simple
 * implementations may store cookies in memory; sophisticated ones may use the file system or

 * Sometimes referred to as *protocol*, A URL's scheme describes what mechanism should be used to

 * supports `http` and `https`. Use [java.net.URI][URI] for URLs with arbitrary schemes.

Use `Response.challenges()` to get the schemes and realms of any authentication challenges. When fulfilling a `Basic` challenge, use `Credentials.basic(username, password)` to encode the request header.
