There isn't any loadbalancing between instances. Am I right ? Could someone tell me if following parameters are useful ? => persistent=1&weight=1&timeout=1&retry_interval=15 Many thanks Hi all,

Many thanks

I knew i was saying something dodgy when i mentioned the A4 cpu. I had an itchy feeling that "proprietary" wasn't the right thing to say. Fixing the post now. thanks man Hey ur right.

Fist of all the A4 is not a CPU, it's a SoC (System on a Chip) that has an ARM Cortex-A9, and a GPU on it. http://www.brightsideofnews.com/news/2010/1/27/apple-a4-soc-unveiled---its-an-arm-cpu-and-the-gpu!.aspx There’s nothing really proprietary about the A4 chip in the iPad.

There's still time for Apple to support it before the iPad releases and/or with a software update.
