I think Neil's point is that "Web servers send headers and content to
browsers" according to *specifications*. There are two of versions of
the spec in the real world: HTTP/1.0 and HTTP/1.1. The former
specification does not specify "Cache-control" or most other caching
directives. To be compliant, you cannot send a 1.1 header from a 1.0
server. Postel's Law and all of that. (But Neil threw "Host" in there
as a 1.0 retrofit, so we're already muddying the waters!)

I reckon that Quixote could be smart enough to always do the right
thing, if told via configuration what version of HTTP was in effect.
