/**
 * The web Response class represents an HTTP response.
 *
 * It holds the [[headers]], [[cookies]] and [[content]] that is to be sent to the client.
 * It also controls the HTTP [[statusCode|status code]].
 *
 * Response is configured as an application component in [[\yii\web\Application]] by default.
 * You can access that instance via `Yii::$app->response`.
 *
 * You can modify its configuration by adding an array to your application config under `components`
 * as it is shown in the following example:
 *
 * ```php
 * 'response' => [
 *     'format' => yii\web\Response::FORMAT_JSON,
 *     'charset' => 'UTF-8',
 *     // ...
 * ]
 * ```
 *
 * For more details and usage information on Response, see the [guide article on responses](guide:runtime-responses).
 *
 * @property CookieCollection $cookies The cookie collection. This property is read-only.
 * @property string $downloadHeaders The attachment file name. This property is write-only.
 * @property HeaderCollection $headers The header collection. This property is read-only.
 * @property bool $isClientError Whether this response indicates a client error. This property is read-only.
 * @property bool $isEmpty Whether this response is empty. This property is read-only.
 * @property bool $isForbidden Whether this response indicates the current request is forbidden. This property
 * is read-only.
 * @property bool $isInformational Whether this response is informational. This property is read-only.
 * @property bool $isInvalid Whether this response has a valid [[statusCode]]. This property is read-only.
 * @property bool $isNotFound Whether this response indicates the currently requested resource is not found.
 * This property is read-only.
 * @property bool $isOk Whether this response is OK. This property is read-only.
 * @property bool $isRedirection Whether this response is a redirection. This property is read-only.
 * @property bool $isServerError Whether this response indicates a server error. This property is read-only.
 * @property bool $isSuccessful Whether this response is successful. This property is read-only.
 * @property int $statusCode The HTTP status code to send with the response.
 * @property \Exception|\Error $statusCodeByException The exception object. This property is write-only.

    /**
     * Sends existing file to a browser as a download using x-sendfile.
     *
     * X-Sendfile is a feature allowing a web application to redirect the request for a file to the webserver
     * that in turn processes the request, this way eliminating the need to perform tasks like reading the file
     * and sending it to the user. When dealing with a lot of files (or very big files) this can lead to a great
     * increase in performance as the web application is allowed to terminate earlier while the webserver is
     * handling the request.
     *
     * The request is sent to the server through a special non-standard HTTP-header.
     * When the web server encounters the presence of such header it will discard all output and send the file
     * specified by that header using web server internals including all optimizations like caching-headers.
     *
     * As this header directive is non-standard different directives exists for different web servers applications:
     *
     * - Apache: [X-Sendfile](http://tn123.org/mod_xsendfile)
     * - Lighttpd v1.4: [X-LIGHTTPD-send-file](http://redmine.lighttpd.net/projects/lighttpd/wiki/X-LIGHTTPD-send-file)
     * - Lighttpd v1.5: [X-Sendfile](http://redmine.lighttpd.net/projects/lighttpd/wiki/X-LIGHTTPD-send-file)
     * - Nginx: [X-Accel-Redirect](http://wiki.nginx.org/XSendfile)
     * - Cherokee: [X-Sendfile and X-Accel-Redirect](http://www.cherokee-project.com/doc/other_goodies.html#x-sendfile)
     *
     * So for this method to work the X-SENDFILE option/module should be enabled by the web server and
     * a proper xHeader should be sent.
     *
     * **Note**
     *
     * This option allows to download files that are not under web folders, and even files that are otherwise protected
     * (deny from all) like `.htaccess`.
     *
     * **Side effects**
     *
     * If this option is disabled by the web server, when this method is called a download configuration dialog
     * will open but the downloaded file will have 0 bytes.
     *
     * **Known issues**
     *
     * There is a Bug with Internet Explorer 6, 7 and 8 when X-SENDFILE is used over an SSL connection, it will show
     * an error message like this: "Internet Explorer was not able to open this Internet site. The requested site
     * is either unavailable or cannot be found.". You can work around this problem by removing the `Pragma`-header.
     *
     * **Example**
     *
     * ```php
     * Yii::$app->response->xSendFile('/home/user/Pictures/picture1.jpg');
     * ```
     *

     * @param string $attachmentName file name shown to the user. If null, it will be determined from `$filePath`.

     *  - `mimeType`: the MIME type of the content. If not set, it will be guessed based on `$filePath`
     *  - `inline`: boolean, whether the browser should open the file within the browser window. Defaults to false,
     *    meaning a download dialog will pop up.
     *  - xHeader: string, the name of the x-sendfile header. Defaults to "X-Sendfile".
