Yes - you're not writing out the cookie. The Session doesn't automatically assign to a cookie. the session object is just the disk file manager. If you want the semi-automatic hander you have to use InitSession.

The easiest way to see whether this is working is to use the Status Form | Show Request Data. When you think you're generating a cookie check the generated HTML and you should see the cookie in the HTTP header.

Your code above could be written:

this.InitSession("wwuser")
Session = this.oSession

*** Force the cookie to be added to header
Response.ContentTypeHeader()

lcValue = Session.GetSessionVar("Value")
IF EMPTY(lcValue)
   lcValue = SYS(2015)
   Session.SessionVar("Value",lcValue)
   lcValue = "New session value created: " + lcValue
ENDIF

Response.Write("Here's the Session Value:" + lcValue)

Nothing else is required.
