Multiple HTTP requests using single HTTPService component

Question

Hi,
I am having one requirement, I need to use a single HTTPService component to send request to a same and single ASP.net multiple times.
How can I acheive that..? I know that I can acheive this by sending one request at a time and after the "result" event is called for the first request then sending the second request and so on...
But if I do so then it will be delayed response as I need to wait until the result handler for the previous request is called...
So how do I do this..?
Any help greatly appreciated....:)
Thanks in advance..
Thanks,

yep, the setting works when set to 10. Seemed to not work when set to 20. Anyways, summary is "long polling" and Flex
or Flash are not good compatriates. So, you will need to work out your own mechanism on the server or client
side to limit the sockets used/wasted. Painful but true.
