是這么個(gè)情況：頁(yè)面操作數(shù)據(jù)完成后，彈出提示成功窗口，截取代碼如下：        If sendflag=1 Then %>            <script language="vbscript">                MsgBox("發(fā)送成功!")                window.location.href="./ExtraServiceSendMms.asp"            </script>        <%else%>            <script language="vbscript">                MsgBox("發(fā)送失敗!")                window.location.href="./ExtraServiceSendMms.asp"            </script>        <%End If如果發(fā)送成功，則跳到ExtraServiceSendMms.asp頁(yè)面，但是瀏覽器的后退按鈕就會(huì)亮起，我按后退鍵的話，會(huì)跳出“發(fā)送成功“這個(gè)腳本，有什么辦法能解決嗎？
