Hi Walt,

This isn't too hard to do. What is hard is using it safely once you've got
it setup. With this, all users have access to all other users' data. Also,
updates to the data could occur at any time, including multiple
simultaneous access to the same data. With one session per user, this isn't
much of a problem. With everyone accessing each other's data, it could
cause problems.

Here is one way to do this. This method puts a collection object into the
application object and adds each session to the collection.

  Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
     Dim colAllSessions As New Collection
     Application.Add("AllSessions", colAllSessions)
     Dim colOldSessions As New Collection
     Application.Add("OldSessions", colOldSessions)
  End Sub

  Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
     CType(Application("AllSessions"), Collection).Add(Session,
Session.SessionID)
     Session("test") = "hello " & Session.SessionID
  End Sub

  Sub Session_End(ByVal sender As Object, ByVal e As EventArgs)
     CType(Application("OldSessions"), Collection).Add(Session.SessionID,
Session.SessionID)
     CType(Application("AllSessions"),
Collection).Remove(Session.SessionID)
  End Sub

---
This can be tested with a test page with this code-behind:
  Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
     Response.Write(Session.SessionID)
     Response.Write("<hr>")
     Dim i As Long
     For i = 1 To CType(Application("AllSessions"), Collection).Count
        Response.Write(CType(CType(Application("AllSessions"),
Collection).Item(i), SessionState.HttpSessionState).SessionID & "<br>")
     Next
     Response.Write("<hr>")
     For i = 1 To CType(Application("OldSessions"), Collection).Count
        Response.Write(CType(Application("OldSessions"),
Collection).Item(i) & "<br>")
     Next
     Response.Write("<hr>")
  End Sub

---
Does this answer your question?
