Hi, I am new to dotnet and of course new to DNN .

I have a question about the UrlRewriteModule httpModule, at the bottom of onBeginRequest function, there codes like this

            If PortalId <> -1 Then
                Globals.SetApplicationName(PortalId)
                ' load the PortalSettings into current context
                Dim _portalSettings As PortalSettings = New PortalSettings(TabId, objPortalAliasInfo)
                app.Context.Items.Add("PortalSettings", _portalSettings)
            Else
                ' other stuff....
            End If

So, the question is why should every request to update the portalSettings?

Thanks in advance
Mike
