you mean upload, do you?

well - my question is a more general one - not related to any library
I know, the apache commons file upload has a way to limit the upload size.
and also the seam s:fileUpload tag has such a setting.
but I am wondering if those settings are making any difference, because the client will always build the request and send the complete very large request to the server (consuming bandwidth), and if the server must process the complete very large request, before it knows that the file is too large, it will also consume a lot of memory and CPU.
I guess that this is the case, because the filesize is not included in any meta-data information.
