Server Side ActionScript - application.onConnect

Hi Guys...

I understand fom the Server Side ActionScript API that the 'application.onConnect' method's parameter settings include a client obect and some optional parameters. It seems to me that for the optional parameters, it has to be a string value. If I were to make a call from from my .as file as follows:

nc.connect(rtmpNow,"anchor");

and the application.onConnect method is as follows in the .as file:

application.onConnect = function(client,nameNow)
{
client.name=nameNow;
//Followed by other lines of code........

}

the above works fine as in I can do a trace to print the value of nameNow. However If I had send it a string variable (initialized), instead of a string value itself, than all I would get is a null in the trace. The API however dosen't seem to explicitly mention that the optional parameters must be string. I hope someone can advise me if it is at all possible to send as arugment to applicaton.onConnect, non string values,variables. Thanks.
