Reset to default 1When Site A tries to fetch content from Site B in a frame, by default, Site B's pages are not accessible due to security reasons(Read this :: https://developer.mozilla/en-US/docs/Web/Security/Same-origin_policy); But using the Access-Control-Allow-Origin header site B can give cross-origin access to specific requesting origins.
Site B can serve its pages to Site A with the following response header:
Access-Control-Allow-Origin: http://www.siteA.
Without site B doing this, you won’t be able to access site A in a frame.
