It is probably debatable if this should use ioutil.Discard or not.

The alternative would be to wire each handler to receive a second io.Writer for errs

This needs a newline at the end and you probably want to print the error as well. Not special casing StatusInternalServerError would also be reasonable thing to do.

Thanks, will go ahead and remove the special case for internal server err - the error we print is pretty much the same as the one below this
