Ah, it looks like you are slightly misunderstanding the BNF descriptions
in the RFC. Only text bounded by "" is meant as exact. The rest is BNF
syntax and 'variables'.
So 'cache-request-directive' and 'cache-response-directive' are not meant
to be actually in the header.
That should be:
"Cache-Control: no-cache;"
probably "Cache-Control: no-cache max-age=1 no-store;" to cover all the
bases.

Apparently "Expires: -1;" is invalid. Better to use an explicit timestamp,
even if its Jan 1970, just to be sure that it works as expected.
Keep in mind. The changes you make will always only be visible after the
previously bad version has been dropped from cache.
