I would like to enable mod_deflate based on the presence and value of a certain cookie.

I know it’s possible to do cookie manipulation and tests with mod_rewrite, but I’m not sure how to do that kind of stuff with mod_deflate.

Is this possible at all? Any pointers?

You could try something like:

SetEnvIf HTTP_COOKIE "NODEF" no-gzip dont-vary
