Session Start firing twice

I have an application that passes in a query string via email link.  In my global aspx file, I check for the query string and store it in a session variable.  Problem is, the response.redirect code is causing the session start to fire twice.  If I remove response.redirect everything works fine..  any suggestions?????


Dim taskOrderName As String = Request.QueryString("TaskOrderName")Dim requestID As String = Request.QueryString("RequestID")


If taskOrderName.Length > 0 Or taskOrderName <> Nothing Then

currentEmailRequest.TaskOrderName = taskOrderName

Me.Session.Add(SessionVars.SessionVariables.CurrentEmailLoginDetails.ToString, currentEmailRequest)

End If

'If requestID.Length > 0 Then

' currentEmailRequest.RequestID = requestID

' Me.Session.Add(SessionVars.SessionVariables.CurrentEmailLoginDetails.ToString, currentEmailRequest)

'End If

instance = WindowsIdentity.GetCurrent()

value = UCase(instance.Name)

loginTime =

If value <> "" Then

Dim ds As DataSet = du.GetDomainUserByID(value)

If ds.Tables(0).Rows.Count > 0 Then

For Each DTTable In ds.Tables

For Each DTRow In DTTable.Rows

With currentDomainUser

.FullName = DTRow("DISPLAYNAME")

.UserName = DTRow("DOMAIN_ID")

End With

Next DTRowNext DTTable

currentDomainUser.ContractorID = 0

If du.IsDomainUserInGroupByName(value, "ADMINS") Then

currentDomainUser.Group = Enums.GroupTypes.InternalAdministrator

Me.Session.Add(SessionVars.SessionVariables.CurrentUser.ToString, currentDomainUser)



currentDomainUser.Group = Enums.GroupTypes.InternalUser

Me.Session.Add(SessionVars.SessionVariables.CurrentUser.ToString, currentDomainUser)

If taskOrderName.Length > 0 Then ' Or requestID.Length > 0 Then




End If

End Sub

Use Server.Transfer instead. Response.Redirect issues a 302 to the browser, causing the second request.

Try this..

Response.Redirect("/TaskOrderStatus/StatusForm.aspx", false)

Check this..

Check the AutoEventWireUp on the pages you are directing to. It may be wired to fire that event if it is set to True.

As an alternate, did you try Server.Transer (although I don't see why that would be any different)

How to Make Web Forms from other Web Forms
In putting together an ASP.NET application for a biz application, we have come to the point where there are three different types of basic forms which have, for the most part, been perfected. Now its is a matter of cloning those forms for various uses and modifying or adding code to suit the particular need. Copy and paste works OK, but there is a lot of changing of certain words, etc. Is there a way in ASP.NET to take these basic forms, turn them into classes or templates, create forms from them, then add or overwrite code? ?
