Firefox 3 beta 3 & Opera 9 uses rpc and FireFox 3 (< beta 3), IE 6 and IE 7 uses ifpc. I want to know, where does the container decide which technique to use?
Currently, dynamic-height is not working in my system in FF 2.0.0.12 but it is working in IE 7, IE 6, opera 9(I don't think about this and FF3 b3 because these uses rpc and hence works perfectly). So, if any bosy gives me details about the ifpc js, it will be very helpful for me.
