PowUpload - File upload component.
PowUpload is an ASP.Net file upload control that enables an
ASP.NET application to capture and save files uploaded to the web server
by a browser. PowUpload is fully compatible with the standard files upload
protocol defined in RFC1867 for the HTML POST Form with the <INPUT
TYPE=FILE> tags.
PowUpload handles and stores the contents of the POST request to a file on the
server hard disk rather than loading it into memory as the built-in ASP.NET
upload support does. PowUpload provides rich server-side progress
indicator that lets users to monitor the progress of their uploads.
