how to create a pop up "now processing" window?

[David]

I would like to pop up a small window that tells the user
to "please wait" while the server completes a long task
(eg. completes an order) and then once the server is done,
close the pop-up and redirect to a results page.

I understand that it's a combination of server-side
redirects and java, but I can't quite understand the order
of events needed.

Any help on how do to this would be appreciated!

Thanks in advance!
David

I've seen it done this way:

By using javascript and layers, you can have a layer either in your popup
window, or in the actual page that contains the data you want to show as
soon as the server is finished processing. The layer should contain a text
like:
"Pleas wait.....". Then at the very end of your page that holds all the
data, you could have a javascript function that hides the layer.
