Is it possible to log more headers for the requests during page-load?

[karfau]

We would like to see specific headers like a cloudflare ray id or cache status in the page-load transactions.

I could not find any documentaion around it beside adding a custom span for requests that are triggered from our own code, which is not the case for most of the requests during page load, which are triggered by preload/prefetch/module loading, etc.

Is there any chance of adding an option to add additional response headers to report?

Hi @karfau

I think you're looking for apmRequest init option. You can find the details in https://www.elastic.co/docs/reference/apm/agents/rum-js/configuration#apm-request

Thx for the link, but that is not what I'm looking for.
I'm looking for reporting headers made by the browser or anything that I'm not in control of, which is happening as part of the initial page load.
For example things like prefetch and preload requests, for which I want to see inside the APM metadata in kibana wether our CDN returned a cache hit or miss header.
