	 * - `follow_redirects`: Should we follow 3xx redirects?

	/**
	 * Send multiple HTTP requests simultaneously
	 *
	 * The `$requests` parameter takes an associative or indexed array of
	 * request fields. The key of each request can be used to match up the
	 * request with the returned data, or with the request passed into your
	 * `multiple.request.complete` callback.
	 *
	 * The request fields value is an associative array with the following keys:
	 *
	 * - `url`: Request URL Same as the `$url` parameter to
	 *    {@see \WpOrg\Requests\Requests::request()}
	 *    (string, required)
	 * - `headers`: Associative array of header fields. Same as the `$headers`
	 *    parameter to {@see \WpOrg\Requests\Requests::request()}
	 *    (array, default: `array()`)
	 * - `data`: Associative array of data fields or a string. Same as the
	 *    `$data` parameter to {@see \WpOrg\Requests\Requests::request()}
	 *    (array|string, default: `array()`)
	 * - `type`: HTTP request type (use \WpOrg\Requests\Requests constants). Same as the `$type`
	 *    parameter to {@see \WpOrg\Requests\Requests::request()}
	 *    (string, default: `\WpOrg\Requests\Requests::GET`)
	 * - `cookies`: Associative array of cookie name to value, or cookie jar.
	 *    (array|\WpOrg\Requests\Cookie\Jar)
	 *
	 * If the `$options` parameter is specified, individual requests will
	 * inherit options from it. This can be used to use a single hooking system,
	 * or set all the types to `\WpOrg\Requests\Requests::POST`, for example.
	 *
	 * In addition, the `$options` parameter takes the following global options:
	 *
	 * - `complete`: A callback for when a request is complete. Takes two
	 *    parameters, a \WpOrg\Requests\Response/\WpOrg\Requests\Exception reference, and the
	 *    ID from the request array (Note: this can also be overridden on a
	 *    per-request basis, although that's a little silly)
	 *    (callback)
	 *
	 * @param array $requests Requests data (see description for more information)
	 * @param array $options Global and default options (see {@see \WpOrg\Requests\Requests::request()})
	 * @return array Responses (either \WpOrg\Requests\Response or a \WpOrg\Requests\Exception object)
	 *
