Reading from Multiple Notecards

I'm in a situation where I would like to have two notecards, for example one for configuration information, and one for authorized users. I realize that the dataserver works as an async event driven process, but looking at the example, I'm still confused as to how to have it read from two different notecards and to know which card I am reading from.

I'm sure this is simple and I'm just having a mental block, but I'd love if someone could point me to an example.

Use different query keys, and check the key returned in the dataserver event. Something like...

key query1;
key query2;

default
{

  event(whatever)
  {
     query1 = llGetNotecardLine("Notecard1", lineNumber1);
     query2 = llGetNotecardLine("Notecard2", lineNumber2);
  }

  dataserver(key id, string data)
  {
    if (id == query1)
    {
      // This data is lineNumber1 in "Notecard1"
    }
    else if (id == query2)
    {
      // This data is lineNumber2 in "Notecard2"
    }
  }
}
