I was involved in the writing of www.e-mol.com and we ran into this same
problem, only with a different situation. E-mol.com allows you to check
your POP3 email from anywhere in the world. Sounded easy enough. But,
what if somebody has 75,000 messages? Well, the browser would time out
waiting for our scripts to get the mail. So, Brian (a different Brian,
not me) wrote a small javascript on the page that updated a process bar.
Then what he did was print a call to the JavaScript to the browser every
few seconds. This gave the client something to look at, and it also let
them know how much progress was being made as well as how much was left.
Worked fantastic for us.
Now, I'm not saying this is or isn't the right way to do it, but it's
working great for us. If you log onto e-mol.com you'll see the progress
bar. If you do a view source after it moves across a bit, then scroll
down, you'll see the calls to the JS. Hope this helps you out.
