How it works
Split alternatives outside quotes, read explicit host/port and max-age, and add max-age to the supplied reference time.
The example advertises h3 on the origin host at port 443 for 3600 seconds, expiring at 01:00 UTC.
Limits
Text inspection only; no connections or protocol support checks. Omitted ma defaults to 86400 seconds. The clear value is recognized; encoded protocol IDs and unknown parameters are retained.
