you mean like i did in the bundle: https://github.com/FriendsOfSymfony/FOSHttpCacheBundle/pull/207/files#diff-d04bcba83a2c4db056b82995f1c24b6bR178 ?

[ddeboer]

Exactly. Saw that and it’s a good idea. For one or another reason my mind still defaults to looking at 2616. 😉

hm, i searched the whole codebase and doc and found no single mention of neither rfc nor 2616. am i missing something or can we close this?

[ddeboer]

Good point, let’s close this.
