Subject Re: [FileUpload] how to disable default output to server file system?
Date Wed, 07 Jun 2006 18:21:28 GMT

uploaded file in a database. It is fine to retrieve the uploaded file as an
byte array in memory then save in the database. But it seems to be still
saved as a file automatically. - Xiaobo
