PowUpload is an http file upload component 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> input field. PowUpload handles and stores the contents of the POST request to a file on the server hard disk rather than loading large file 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, also it include AJAX progress bar.
