Hello @ddavila0 , What do you get when running the `davix-cp` client? E.g.: `davix-cp --trace header zero_bytes https://gftp-2.t2.ucsd.edu:1094/store/user/ddavila/newdir/zero-bytes` Just a guess: perhaps there's some unpleasant interaction between the `XrdHttp` component and the `Content-Length: 0` header. -- You are receiving this because you are subscribed to this thread.
