Displaying output of command line over HTTP in real time

[James Davis]

I've got a command line program that I wish to launch from a mod_perl
script. The program can take it's time to execute and the partial output
is useful so I'd like to be able to display the output piped through
HTTP as and when it becomes available. I'm sure I've seen this done
before :-)

What's the magic I need?

James
