In r617822 I introduced the function is_idempotent as a static function to mod_proxy_ajp.c. It seems quite clear that others could benefit from this function as well. To what scope should I move this function? Should I move it to proxy_util.c and thus extending the proxy API or should I move it to the http module (e.g. http_protocol.c) and thus extend the core API? Thoughts?
