How to stop loading scripts if Internet Explorer 6 (7/8)?

Question

JavaScript

I want to stop / not load other scripts in the head (for example, angular.min.js) if the browser is < IE 9.
To do this, <!--[if lt IE 9]>I tried the standard methods using: warning.js, ie-upgrade-modal.js, browser-update.org and such advice from the stacks - // special not IE6 stuff.
Internet Explorer 8 still loads the rest of the scripts.

Cut on the server side by user agent.
