Forum Redirect Pages - How Do They Do It?

Ah, unfortunately the meta redirect is completely unsuitable in my case, as the data will be returned within a variable timeframe of anywhere from 0.5 to 10 seconds. I never know exactly how long it will take.

Do you by any chance know of any tutorials or anything online that demonstrate an AJAX redirect system? We are already using JQuery and this would be the preferable framework to use.
