The component at the top is Uplpu, the Shockwave Flash file upload component.
Choose 'browse' to select a file on your system followed by 'upload' to upload
that file.
The second component is a simple text output screen to display the various
events that Uplpu sends. See the manual for a description of these events.
The following table displays what files are allowed for this demo.
Files that arrive at the server will be erased immediately.
