Are the values of _adf.ctrl-state and window.name assigned uniquely?

Question

Hi
I found that javaScript window.name always returns the same value with the value of URL parameter _adf.ctrl-state subtracted by 3.
For example, if the adf.ctrl-state is xxxxxxxxx4, window.name returns xxxxxxxxx_1.
I want to utilize these values to handle windows with javaScript programming.
But I wonder if these values are assigned uniquely or not.
By chance they can be equal to those of previously opened window?
Regards,
Kenji

Thanks for your responses.
My use case is as follows.
There is an ADF application having two pages, say page A and B.
A user can open page A on multiple windows simultaneously, while page B is allowed to be opened on only one window per session.
When a certain event is kicked in page A and there is no window showing page B, page B is opened on a new modeless window.
However, if there is already a window showing page B when the event is kicked in page A, a new page B window should not be opened but the event should be propagated to the existing page B window and refresh it.
As far as I know, ADF does not provide this kind of inter-window communication functionality.
Thus I thought of using JavaScript.
When page B is opened, the name of the window showing it is added to the session attribute (with a key of "page B", for example).
Depending on whether session.getAttribute("page B") returns null or not null, the event in page A is resulted in opening a new page B window or refreshing the existing page B window, respectively.
I admit that this is not cool.
I do appreciate if someone show me a better solution.
