چی چرا اشتباهه؟!!!
مسلمه که Redirect برای هدایت کاربر به یک صفحه ی دیگه استفاده میشه و کاری با Response نداره.
این کد داخلی Redirect هست که مایکروسافت نوشته.
با دقت نگاه کنید تا دلیلش رو متوجه بشید:
Public Sub Redirect(ByVal url As String, ByVal endResponse As Boolean)
If (url Is Nothing) Then
Throw New ArgumentNullException("url")
End If
If (url.IndexOf(ChrW(10)) >= 0) Then
Throw New ArgumentException(SR.GetString("Cannot_redirect_to_newline"))
End If
If Me._headersWritten Then
Throw New HttpException(SR.GetString("Cannot_redirect_after_headers_sent"))
End If
Dim page1 As Page = TryCast(Me._context.Handler,Page)
If ((Not page1 Is Nothing) AndAlso page1.IsCallback) Then
Throw New ApplicationException(SR.GetString("Redirect_not_allowed_in_callback"))
End If
url = Me.ApplyRedirectQueryStringIfRequired(url)
url = Me.ApplyAppPathModifier(url)
url = Me.ConvertToFullyQualifiedRedirectUrlIfRequired(ur l)
url = Me.UrlEncodeRedirect(url)
Me.Clear
If (((Not page1 Is Nothing) AndAlso page1.IsPostBack) AndAlso (page1.SmartNavigation AndAlso (Me.Request.Item("__smartNavPostBack") Is "true"))) Then
Me.Write("<BODY><ASP_SMARTNAV_RDIR url=""")
Me.Write(HttpUtility.HtmlEncode(url))
Me.Write("""></ASP_SMARTNAV_RDIR>")
Me.Write("</BODY>")
Else
Me.StatusCode = 302
Me._redirectLocation = url
Me.Write("<html><head><title>Object moved</title></head><body>" & ChrW(13) & ChrW(10))
Me.Write(("<h2>Object moved to <a href=""" & HttpUtility.HtmlAttributeEncode(url) & """>here</a>.</h2>" & ChrW(13) & ChrW(10)))
Me.Write("</body></html>" & ChrW(13) & ChrW(10))
End If
Me._isRequestBeingRedirected = True
If endResponse Then
Me.End
End If
End Sub
موفق باشید.
