Example demonstrates how to use Java Script features to show Progress bar
Window and "Cancel Upload" button.
To synchronize the progress bar with the upload process the same ID must be
passed to both files.
If Java Scripts disabled then "Cancel" button will be hidden and Progress bar
won't be shown.
Click "Stop" at your browser while upload - example will save only fully loaded
files and shows saved files names in Progress window!
Note! Choose large files to see a progress bar.
