Webview - refused connections

I entered the example
Webview url=“http://www.openhab.org” height=5
from the documentation and this works,
but if I change the URL to BBC or even my own website I get a connection refused message.
How does the request sent to the webserver look different to a normal browser request ?
Is openhab.org configured specially to allow this ?

Just add .htaccess file to your directory

Add these lines to CORSify your server for everyone.

Header set Access-Control-Allow-Origin “*”
