Is it possible to access external https urls under krpano testing server?

krpano 1.22 limited access to external URL's

To load the script, you can use "sameorigin: false" on the HTML page where krpano is included, for example:

    <script>
        embedpano({xml:"tour.xml", bgcolor:"transparent", target:"pano", html5:"only", mobilescale:1.0, sameorigin:false, passQueryParameters:"startscene,startlookat"});
    </script>

Alternatively, you can try running a local server with HTTPS using something like localhost over SSL or the mkcert tool. This usually solves mixed content issues.
