Well technically we use multipart/form-data, so the file that is appended is actually a part with its own content-length independent of the http message body. 

It's a fair point though that this value is the network size which is not necessarily the disk size . It just so happens we only support the cases where hey correspond (on the http side). You can't add a gzip encoding to a part for example. You could only do that as a special mime-type.
