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

Answer 1

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.
