    https://github.com/apache/trafficserver/pull/1067
  
    In our production, some servers return multiple Cache-Control headers.
    
    For example, if the following configurations are applied to apache httpd
    ```
    Header always set Cache-Control "public"
    ExpiresActive On
    ExpiresDefault "access plus 1 days"
    ```
    then the server returns the following headers.
    ```
    Cache-Control: public
    Cache-Control: max-age=86400
    Expires: Tue, 04 Oct 2016 12:25:44 GMT
    ```
