Thank you for looking at this.

Unfortunately I don't think this will work as written - see inline.

There may be a way to fix it though - more discussion needed

The Body is used to upload objects so could easily be a 5G file which we don't want to buffer in memory.

Where are you seeing this problem?

There are quite a few possible workaround, but to suggest one I need more context.

Sorry for my very late rseponse. I missed it earlier

I see the problem is fixed in d2de41c to some extent. Maybe it should always Seek(0, io.SeekStart) , not only in 401 ?
