request.putVariable2InSession.classname=com.ai.parts.SessionVariablesPart
request.putVariable2InSession.variableName=var1
request.putVariable2InSession.newVariableName=var2

The above code when embedded in a pipeline will take "var1" from the hashtable and places it in the session as "var2". If newVariableName is not mentioned then it will just put it as variableName
