Step 4: Create the BDL session initiator function and instantiate a new session

In your BDL function declared as session initiator, you must:

• Handle the creation of the session.

• Fill the state variable before returning from the function.

• Store the state variable in a database based on the state variable (in order to keep the session across consecutive requests from the same client).

FUNCTION GetInstance()
  # Generate an unique string (can come from a database table id)
  LET ServiceState = com.Util.CreateUUIDString()
      ... Store ServiceState value into database or use directly a 
          database table entry to hold the session
END FUNCTION
