/**
 * @assertion Future<HttpClientResponse> redirect([
 *  String method,
 *  Uri url,
 *  bool followLoops
 *  ])
 * Redirects this connection to a new URL. The default value for method is the
 * method for the current request. The default value for url is the value of the
 * HttpHeaders.locationHeader header of the current response. All body data must have
 * been read from the current response before calling redirect.
 *
 * All headers added to the request will be added to the redirection request.
 * However, any body sent with the request will not be part of the redirection
 * request.
 *
 * If followLoops is set to true, redirect will follow the redirect, even if the
 * URL was already visited. The default value is false.
 *
 * The method will ignore HttpClientRequest.maxRedirects and will always perform
 * the redirect.
 * @description Checks that this method redirects this connection to a new URL
