Fixed

• Replace multiple slashes at the beginning of a path with a single one to avoid open redirects
• Avoid updating ResponseWriter.Status() if the status has already been written when ResponseWriter.WriteHeader() is called twice

Changed

• ResponseWriter now only implements http interfaces (Flusher, Hijacker, CloseNotifier) if the wrapped http.ResponseWriter does. This is a breaking change to make ResponseWriter's interface support more accurate

Added

• ResponseWriter now implements io.ReaderFrom to more efficiently send responses via io.Copy
