Original GitHub issue: https://github.com/binwiederhier/ntfy/issues/351

Cloudflare apparently adds a Priority: u=... header to requests, which ntfy rejects with 500 invalid priority (should be a 400). This is a new HTTP standard (https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-priority) that is emerging.

We should ignore header values that start with u=. It is quite unfortunate that the name conflicts like this.

This ticket (https://github.com/binwiederhier/ntfy/issues/353) has a full dump of the Cloudflare request showing the Priority: u=3 header.
