Seems like your own module would be small and straight forward. There is a patch floating around for mod_setenvif that adds a filter for it to act on response headers. That may could be used, depending on the order things happen. I'd still like this patch to be committed, I can resubmit, if you want to take a look.
Of course, this would be easy to do in lua... ;) -- Brian Akins Chief Operations Engineer Turner Digital Media Technologies
