Which is fine as there is no doubt what the requestor meant, but not
required by the specs even if roubust and forgiving HTTP-date parsers is

And sorry, my wording was slightly bad before. An invalid

result in 304, not ignored. The difference is when combined with
If-None-Match or other conditionals.
