Does Session.SessionID change on every postback for the same user?

pzn3xq

Hello, In my pageInit I have mSesID=Session.SessionID.ToString(); Each time a postback occurs, I receive a new sessionID #. Is this correct? Shouldn't the session be the same session value even during postbacks for the same user? I assumed it would always be the same value, but I'm probably wrong. Thanks

I'm not sure but you could easily create a new guid and store that in session. Then you would have an identifier.

I didn't get any requirements for the signature

According to MSDN it should be unique for the session. See Here[^]

Yusuf Can I help you?

You will receive different sessionID while you havent save something in the session Once you save something in the session, the sessionID will remain the same

Protected Sub Page\_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
    Response.Write("Init " & Session.SessionID)
End Sub

Protected Sub Page\_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    If Not Page.IsPostBack Then Session("X") = "X"
End Sub
