Create of Sub domains

[sudeepica.t]

Can we create sub domains in flex as www.xxx.abc123.com where www.abc123.com is the main domain when a user named 'xxx' gets registered, so that the user can access all of his information in the url www.xxx.abc123.com
I want all this to be done dynamically and programmatically and without using any CPanels for creating sub domains. Is it possible?

I don't think Flex/SWF can do such thing...

as CyanBlue said, Flash can't do something like that. However something like python might.
