How to prevent script loading in different domain
<p>I have <code>&lt;script src="bla"&gt;&lt;/script&gt;</code> that can be loaded in several domains.
I want to know if there is a way to control the domains it will be loaded  on.
To clarify: My script is server-side rendered, so basically I can return empty string if the requested domain is invalid.</p>

<p>This is to prevent from other sites embedding my script.</p>

<p>Thanks!</p>
