What this tester can and cannot establish
If a page visibly renders, the browser allowed that preview. A blank iframe may be blocked by X-Frame-Options, CSP, login or third-party cookies. An iframe load event alone is not proof that the page loaded successfully.
This is a real browser preview, not a server-side security scan. A site may allow embedding on ArsKhan but restrict embedding from another origin. Some sites intentionally refuse all framing to prevent clickjacking. Browser policies and authentication can also affect the result.
The preview uses a sandbox that blocks top-level navigation, popups and same-origin storage access, so some websites may appear broken here even when a normal iframe works. For security, scripts cannot remove this restriction from ArsKhan's preview. For a definitive diagnosis, check your browser developer console and the target page’s response headers for X-Frame-Options and Content-Security-Policy frame-ancestors.
The address is not submitted to an ArsKhan API. Your browser contacts the target website directly, which may record the request and your IP address under that site's own policies.
