0 -> return uwsgi header + rpc response
1 -> return raw rpc response
2 -> split PATH_INFO to get func name and args and return as HTTP response with content_type as application/binary or Accept request header (if different from *)
3 -> set xmlrpc wrapper (requires libxml2)
4 -> set jsonrpc wrapper (requires libjansson)
