| This sample allows you to return a message to the user after they have
clicked on a hyperlink to download a file.
Note: This message is returned regardless of the success of the download.
This just lets the user know that action was taken after they chose where to save their file.
The reason for this is that currently you can only measure success on passing
the data to IIS. After that, there is no guarantee that the bits have actually
been written successfully to the user's disk. There could be IIS, network, or
local PC problems that occur afterwards over which we have no control.
The only way to guarantee this is via client-side tools such as SA-JFile or SA-XFile that receive the bits,
and then send back an acknowledgement when the data is persistently stored on
the user's disk. SA-JFile is a java-based client-side applet which may be used on a variety of platforms. SA-XFile is an ActiveX applet which can be used in conjunction with any ActiveX client program, such as Microsoft Internet Explorer or Microsoft Office.
