the PC will 'bind' one port to one application, in this case it will 'bind' one port to my space, and another to AO.

there are 65 536 ports, 2 to the 16th power, so it is unlikely to run out of options


the reasons for doing this are so that you get replies from AO onto the page you have opened FOR AO

otherwise you would end up with all data coming back to the PC, and all going to the same window, irrespective of content

on another level
I think you have been here before
and are just yanking our chain, so to speak
