Nirvana RTD : Session Creation

Whenever the RTD Function is entered into a cell, the Nirvana RTD server must deliver the required data to that cell. Often it is the case that many cells require different data from the same event published to a Nirvana Channel. In this case each cell shares the same session and subscription rather than creating a new session per cell.

Only if a different value for the RNAME field is specified will the Nirvana RTD server create a new session. So if the user specifies a user name for the session then a new session will be created unless one already exists for the same realm and user.
