Apologies for tardy response - I was hoping someone else who'd done something similar may have popped in.

Have you read up a bit on caching options?

Much of the magic of the deepliquid page seems to be javascript - the PHP side of things looks to be fairly straightforward (I would think).

You might want to use the Input class rather than fiddling with $_POST directly.
