Err, no, I would not store it anyways, the question is, how do I give the
sum to the client? (since I'm already using the
stream to return the value?)
Or do you mean that when that particular format is used, then only the
checksum is returned?
The problem of such an approach is that between the download and the
checksum is requested
something in the data (or in the configuration) might have changed, thus
making the checksum
useless
