There is, but there is a clear existing convention for using the X- prefix
in Wikimedia-specific headers, so I think local consistency trumps the IETF
recommendation. We currently have X-Analytics, X-Trusted-Proxy,
X-Wikimedia-Security-Audit, X-Pass-Stream, X-Carrier, X-Carrier-Meta,
X-CDIS, X-Subdomain,
X-Orig-Cookie, X-MediaWiki-Original, X-WMF-NOCOOKIES, X-ZeroTLS,
X-Forwarded-By, X-CS2, and X-Subdomain. And this is not an exhaustive list.

Yup, and this seems to include vendor usage in addition to discouraging
continuation of the terrible legacy of X-Forwarded-For, x-gzip, etc...
headers where X- headers ended up de facto standards.

https://tools.ietf.org/html/rfc6648

I suggest VND.Wikimedia.Debug:

But Wikimedia-Debug would also be acceptable; but might want to submit
it to the registry.

Isn't there a recommendation not to use the X- prefix for any new headers?

[Wikitech-l] X-Wikimedia-Debug, your new secret side-kick

[Ori Livneh]

Hey all,

I'm writing to let you know of a cool new facility for debugging MediaWiki
code on the Wikimedia production cluster -- the X-Wikimedia-Debug
 HTTP header.

By setting this header on requests to Wikimedia wikis, you can:

- Bypass the cache.
- Force Varnish to pass your request to a specific backend server.
- Profile request and log profiling data to XHGui.
- Turn on all log channels and send log messages to a special view in
Kibana / Logstash.
- Force MediaWiki to process the request in read-only mode.

And the best part: there are browser extensions for Chrome and Firefox that
provide a friendly user-interface for these features:

Cool? Cool.

Read the docs on Wikitech
 for more
information.
