How do I detect that a resource failed to render and take appropriate action?

I have a resource included as follows:

<div data-sly-resource="${ 'resource-name' @ resourceType='path/to/resource'}"></div>

In some cases, that resource is failing to load and no HTMLis being rendered. How can I detected that failure and take action?

Preferably, I'd like to return the response as normal and set an HTTP header.

Thanks for your help!
