I've seen people use Javascript (changing text on a page), using
redirects, etc to handle the case where a "please wait" screen has to
be shown on a submit.

Are there best practices on doing this with CGI::Application?

Here's the problem:
1) mode1 - displays a form with submit.
2) mode2 - after user hits submit, would like to display the page with
infomation trickling to the page - "done step 1, ... done step2 ..."
Once the job is complete, would like to display "mode3" - the results page.

I've seen an archived message in this list - using "headers - none",
and  then print data that will now directly go to the client browser
page.
Others have suggested using Javascript to put up a generic
"working..." sign in a <div> section on the page.

I am looking for any other ideas or thoughts.
