In a similar fashion, you are allowed to access the HTTP headers of the response that was sent to the client. These variables are not available at all times—they will only carry a value after the response is sent, for instance, at the time of writing messages in the logs:
|
Variable |
Description |

$sent_http_content_type |

|
$sent_http_content_length |
Value of the Content-Length HTTP header informing the client of the response body length. |
|
$sent_http_location |
Value of the Location HTTP header, which indicates that the location of the desired resource is different from the one specified in the original request. ... |
