How do I get the Origin request header from cross-domain AJAX requests in Rails?

You can achieve this in the controller by using: <pre class="prettyprint"><code>request.headers['origin'] </code></pre> Note: You will need to make certain changes in certain config files for your application to be able to respond to a CORS request. Hope you've got that covered.

It seems like <code>request.origin</code> also works directly in recent rails versions. (at least Rails 6)
