Before Microsoft gave us the XMLHttpRequest, and before IFRAMEs were everywhere, this is exactly how, and with FRAMESETs and target="" one could track session length, reload other parts of a page after some given time, allow forms to interact with complex flows and various other things. The "virtually invisible frame loading in the background" trick is going to be around for a long-term and seems destined to be re-learned many times over. |
