Thank you, Bogart.
Now I have a different question to beg help from you guys. I want to print a
clean 'Thank you' page after a user hit the 'Submit' button. But I don't know
how to get rid of the other stuff (resulting from the form generated earlier)
that was already on the screen. Here is the code snippet that failed me.
if (param("Action") eq "Submit") {
Print_thank_you();
}
sub print_thank_you {
Print header;
Print start_html("Thank You");
Print end_html;
}
Thanks for your time and help,
Bob Xiong

Like John said, a button can be scripted to request a URL when clicked.
<input type="button" value="Click Me" onclick="location.href =
'http://whatever'">
If you need to dynamically locate or process the file on the server
side you can do something like this:
(It's PHP code. Sorry. The HTTP part is the good stuff.)
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-
check=0");
header("Cache-Control: private",false); // required for certain
browsers
header("Content-Transfer-Encoding: binary");
header("Content-Type: " . $mimetype);
header("Content-Length: " . $filesize);
header("Content-Disposition: attachment; filename=\"" . $name .
"\";" );
... followed by printing "\n\n" and the contents of the file.
