 * In which file or where wordpress adds “cache-control” header?
    I disabled all
   my plugins to find out the reason of some headers, and discovered that WordPress
   always adds `cache-control: no-cache` header.
 * [This post](http://wordpress.stackexchange.com/questions/167128/prevent-wordpress-from-sending-cache-control-http-header)
   recommends filter for `wp_headers`, but i prefer to just remove it from wordpress
   code file to do not spend CPU for filters.
    Also, this solution not working for
   me on latest wordpress.
 * I need to configure my headers in my own way so how to prevent wordpress from
   adding it, in which file it is set?

 * In git repo i’ve searched for this http header.
    Filter name has changed. Correct
   code for this hack:
 *     ```
       add_filter('nocache_headers', 'wpfck_nocache', 99, 1);
       function wpfck_nocache($headers)
       {
           unset($headers['Cache-Control']);
           unset($headers['Expires']);
           unset($headers['Pragma']);//carefully
           return $headers;
       }
       ```
   
 * If you need to wipe it out just modify function at `wp-includes/functions.php:
   1024`
