Got some vb.net code that authenticates a user, and sets a session variable, works fine. Wrapped all the security stuff into a Class to maintain in one place rather than duplicating across many pages. Getting the message that "Request not available within
this context" when trying to capture the visitor's IP. Works fine inside the Page_Load event, just not inside a Class called from within Page_Load.
Is the Request object not available within a Class? (Would I have to pass the object to the Class?)
Here is a snip of the codebehind, the class, and the error - thanks for any insight & discussion, cheers!
=== index.aspx.vb ==========================================
Imports MyApp.SecurityCheck
Public Class index
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'--------- this works fine when uncommented
'If Session("VisitorIP") Is Nothing Then Session("VisitorIP") = Request.UserHostAddress.ToString()
Dim MySecurityCheck As New SecurityCheck
MySecurityCheck.RequiresAuthentication(True)
MySecurityCheck.RunChecks()
End Sub
End Class
=== SecurityCheck.VB ==========================================

Public Class SecurityCheck

Public Sub RunChecks()

'--------- this blows up when uncommented, unless session variable already set
' If Session("VisitorIP") Is Nothing Then Session("VisitorIP") = Request.UserHostAddress.ToString()
End Sub
End Class
=== the error message ==========================================
