 /**
  * 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:
  * <ul>
  * <li>Apache: {@link http://tn123.org/mod_xsendfile X-Sendfile}</li>
  * <li>Lighttpd v1.4: {@link http://redmine.lighttpd.net/projects/lighttpd/wiki/X-LIGHTTPD-send-file X-LIGHTTPD-send-file}</li>
  * <li>Lighttpd v1.5: {@link http://redmine.lighttpd.net/projects/lighttpd/wiki/X-LIGHTTPD-send-file X-Sendfile}</li>
  * <li>Nginx: {@link http://wiki.nginx.org/XSendfile X-Accel-Redirect}</li>
  * <li>Cherokee: {@link http://www.cherokee-project.com/doc/other_goodies.html#x-sendfile X-Sendfile and X-Accel-Redirect}</li>
  * </ul>
  * 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.
  *
  * <b>Note:</b>
  * This option allows to download files that are not under web folders, and even files that are otherwise protected (deny from all) like .htaccess
  *
  * <b>Side effects</b>:
  * 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.
  *
  * <b>Example</b>:
  * <pre>
  * <?php
  *    Yii::app()->request->xSendFile('/home/user/Pictures/picture1.jpg',array(
  *        'saveName'=>'image1.jpg',
  *        'mimeType'=>'image/jpeg',
  *        'terminate'=>false,
  *    ));
  * ?>
  * </pre>
  * @param string $filePath file name with full path
  * @param array $options additional options:
  * <ul>
  * <li>saveName: file name shown to the user, if not set real file name will be used</li>
  * <li>mimeType: mime type of the file, if not set it will be guessed automatically based on the file name, if set to null no content-type header will be sent.</li>
  * <li>xHeader: appropriate x-sendfile header, defaults to "X-Sendfile"</li>
  * <li>terminate: whether to terminate the current application after calling this method, defaults to true</li>
  * <li>forceDownload: specifies whether the file will be downloaded or shown inline, defaults to true. (Since version 1.1.9.)</li>
  * <li>addHeaders: an array of additional http headers in header-value pairs (available since version 1.1.10)</li>
  * </ul>
  * @param string $filePath
  * @param array $options
  * @return null
