# Origin security

### Identification headers

Cloudimage allows you to set up one or many ***global headers*** which are sent to the origin on every request.

You need to enter the `name` and `value` of the header(s) to send. All these headers will be automatically sent for each request made with your token which allows you to set up your origin to accept only requests containing these headers.

{% hint style="info" %}
In the value field, you could use the following variables:

* `{{header.host}}` will allow you to forward the `HOST` header to your origin;
* `{{req.ip}}` will allow you to forward the client's IP address.

If you have been a Cloudimage customer before 01/01/2023, please contact us to enable this feature.
