Custom HTTP Headers Missing

I’m adding custom HTTP headers to a few of my blog posts as follows

add_action('template_redirect', 'gd_custom_http_headers');

function gd_custom_http_headers() {

   // our logic based on post ID
   header('X-Robots-Tag: nofollow');

   // sometimes
   header('X-GD-API-KEY: xxxxxxxxxxxxxxxxxxxx');

}

1. It works fine initially “with” and “without” cache buster parameter swcfpc=1

2. After few days (2-3 days), all my custom headers were missing. However, if I log in and add swcfpc=1 parameter, I could see my custom headers correctly.

3. When I hit “Purge whole cache”, it started working again temporarily for 2-3 days.

I’m not sure where I’m doing it wrong.

Thank you
