Inflicting things on the browser is javascript's job. The cgi server has no connection with the user's browser except for what's in the web page. See perldoc CGI for help on writing javascript from perl. It's no big trick - you just write it along with the rest of the text.

You might look at "server push", but that's an old idea nobody liked.

Update: I forgot, at first, that if you haven't finished printing the page, you can print messages to it periodically.
