Asp.net 在代码隐藏中使用VB在google chrome中如何关闭网页

嗨，在我的网站上有一个关闭按钮，点击它我想清理缓存并关闭网站

  Public Sub CloseIM_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles button


        Try
            Session.Item("UserName") = Nothing
            Session.RemoveAll()

            Response.ExpiresAbsolute = Now().Subtract(New TimeSpan(1, 0, 0, 0))
            Response.Expires = 0
            Response.CacheControl = "no-cache"
            Response.Write("<script language='javascript'> { self.close() }</script>")
'' i used above line to close but it is not working in google chrome working properly in IE all versions

End sub

我使用Response.Write{self.close}来关闭，但它在Google chrome中不起作用
