If it is really a dynamically generated object at the server, such as
a CGI program/script, or PHP, then that would be the effect of being
rewritten.

Perhaps what he had in mind was a big CSS file that had several variable
references within, and an @import for another CSS file that would have
some kind of settings for those variables. The big file can be cached
because it is static and never changes, while the other file might be
small and perhaps dynamically generated. Or maybe he will set those
variables in the HTML, such as within <style></style> if CSS did have a
way to set and use variables. It's an interesting concept. I'm not
sure how generally (as in for everyone) useful it would be.
I've found that some of what would otherwise be complex things can in fact
be done fairly simple by just referencing multiple classes from HTML elements
and letting the effects of those classes mix appropriately. I don't know
what the OP ultimately wants to accomplish, so I don't know if this would be
at least some way around his issue, or not.
As far as I know, there is no need for the file extension to be ".css" for
a file to be used as style. It just needs the correct MIME type and be
referenced in the appropriate context. If the extension is ".php" then
he could generate it with PHP easily enough by having the server treat it
as such.
