Prevent wordpress setting Cache-Control HTTP header

  • 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 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
