Change the X-Frame-Options to allow all domains

Question

I am trying to use some site of mine as an iframe from a different site of mine.

My problem is- the other site is always consistently changes his IP address and does not have an domain name.

So, I read that you can allo a specific domain by adding this lint to the /etc/nginx/nginx.conf:

 add_header X-Frame-Options "ALLOW-FROM https://subdomain.example.com/"; 

My question is: It is possible to allow my site to be imported as an iframe from all IP addressed and domains? What should I write in order to achieve this?

I am using Ubuntu 16.04 and nginx 1.10.0.

Answer 1

If you set it, then you can only set it to DENY, SAMEORIGIN, or ALLOW-FROM (a specific origin).

Allowing all domains is the default. Don't set the X-Frame-Options header at all if you want that.

Note that the successor to X-Frame-Options — CSP's frame-ancestors directive — accepts a list of allowed origins so you can easily allow some origins instead of none, one or all.

Answer 2

ALLOWALL is the default value.

Sometimes frameworks MVC such as Rails, Laravel, Django and so on, set a X_FRAME_OPTIONS to SAMEORIGIN so someone might need to reset it to the origin ALLOWALL value.
