I noticed this question, which discusses various ways to alter HTTP Response Headers.

Where would I be able to execute:

$response->headers->remove('X-Frame-Options');

I attempted to place this within my THEMENAME.theme file, but perhaps I am not doing it right because $response is not defined where I am using it.

Where does $response come from?

Where can I execute $response->headers->remove('X-Frame-Options');?

Note: I understand the risks of removing the HTTP Header. This is for development/testing purposes only.

  • Sounds like it should be an EventSubscriber to me. – Kevin Jul 7 '17 at 21:41
  • @Kevin, are custom modules required for EventSubscribers? – Raphael Rafatpanah Jul 7 '17 at 22:41
  • Yes. Check some of the docs and blogs about them. – Kevin Jul 7 '17 at 22:43
  • @Kevin, can you clarify where a custom service should live relative to the root Drupal installation? I've tried from the root level and also from /modules, and Drupal is not picking up my Event subscription. – Raphael Rafatpanah Jul 8 '17 at 2:06

Got it!

From these two sources:

I realized that I was missing a mymodule.info.yml file.

mymodule 
  ├── mymodule.info.yml 
  ├── mymodule.services.yml 
  └── src 
    └── EventSubscriber 
      └── RemoveXFrameOptionsSubscriber.php

Then, go to /admin/modules in the backend (Extend tab) and install the new module & clear all caches afterwards.

Woohoo!
