## HTTP Trace

HTTP tracing can be enabled by using [`mc admin trace`](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md#command-trace---display-minio-server-http-trace) command.

Example:

```sh
minio server /data

      } // else no check necessary, all index values are valid
      ArrayReference<? extends L> existingRef = locks.get(index);
      L existing = existingRef == null ? null : existingRef.get();
      if (existing != null) {
        return existing;
      }
      L created = supplier.get();
      ArrayReference<L> newRef = new ArrayReference<>(created, index, queue);

                        .setException(e));
            }
