I am using 2 instances of an XMLHttpRequest object to make simulataneous calls. According to the monitoring on the emulator the requests are made concurrently but they reach the server serially.

So I was wondering:
a) Is this supposed to be possible?
b) Do people think this is a a bug (in say the emulator or my coding)

The reason for me wanting to do this is that I want to implement cometd/bayeux or DWR like streaming over http which (I think) requires one (long lived) connection for outbound and one of inbound.
