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.
