How to Resolve the \'X-Frame-Options\' SAMEORIGIN Error When Embedding iframes?

Resolving the 'X-Frame-Options' Error in iframes

In scenarios where an iframe request prompts the error "Refused to display...because it set 'X-Frame-Options' to 'SAMEORIGIN'", modifying the X-Frame-Options header within the iframe itself is impractical.

The X-Frame-Options header is a server response that defines whether or not an iframe can embed content from another origin. In this instance, the error indicates that the server hosting the content (google.com.ua) has restricted external embedding by setting the header to SAMEORIGIN. Therefore, attempting to embed the resource in an iframe from a different domain will fail.

To rectify this issue, it is crucial to understand that you cannot set X-Frame-Options directly within the iframe's JavaScript code. Instead, the header must be configured on the server hosting the embedded content.

If you have control over the server, you can modify the X-Frame-Options header in the response to allow external embedding. In most cases, setting the header to SAMEORIGIN-NONE will allow the iframe to embed the content from different origins.

For further insight into X-Frame-Options, refer to Mozilla Developer Network's documentation on the X-Frame-Options response header.
