INC Website Embed Limitations

WEBSITE EMBEDDING LIMITATIONS

Some websites prevent IFrame embeds on remote sites, which cannot be circumvented. When you try to embed such protected URLs, errors like 401 (unauthorized) or a "Refused to Connect" message will be shown instead of your desired output.

✅ Possible Workarounds:

  • If available, consult your external source website support to check if any iframe-referrals are allowed. Some services offer specialized data widgets for that purpose or provide authorized token-URLs that you can use.
  • If you have access to whitelists on your source website, try to allow the *.luware.cloud domain for external embedding / referencing.

 There are two types of HTTP headers in websites that control iframe loading:

X-Frame-Options: DENY

Content-Security-Policy: frame-ancestors 'none'

The HTTP Content-Security-Policy specifies valid parents that may embed a page using <frame>, <iframe>, <object>, or <embed>.

A website header called x-frame-options specifies the access prevention, determined via the following values: 

  • if set to DENY the site isn't allowed to be loaded in iframe 
  • if set to SAMEORIGIN the page can only be embedded in a frame on a page with the same origin as itself.
  • if set to ALLOW-FROM the page can only be displayed in a frame on the specified origin. This only works in browsers that support this header.
