about the directive

Do you have any supporting links, references, or citations?

paragraph of must revalidate exists here, with no header

content/files/en-us/web/http/reference/headers/cache-control/index.md

Line 147 in fe28ff1

The `must-revalidate` response directive indicates that the response can be stored in caches and can be reused while [fresh](/en-US/docs/Web/HTTP/Guides/Caching#fresh_and_stale_based_on_age). If the response becomes [stale](/en-US/docs/Web/HTTP/Guides/Caching#fresh_and_stale_based_on_age), it must be validated with the origin server before reuse.

Do you have anything more you want to share?

the listing also does not follow the ordering in the Directive Request/Response table above, while this is minor it could aid in making the content more "followable" when "jumping" from one section to another. Alternatively, use of hash-link in the markdown to jump to section directly could also be helpful.

but this is all minor compared to not even having the setion header :)
