用js实现比较简单.
把要转向的页面post到这个跳转页面.
给你个参考代码吧.
response.write "<div id='msg'>登录成功!,系统将在3秒后跳回...</div><script language='javascript'>var timeout=3;var redirectpage='';function redirect(page,sec){redirectpage=page;if (sec!=null){timeout=sec;}if (timeout<=0){window.top.location=page;}else{if (document.getElementById('msg')!=null){document.getElementById('msg').innerHTML='登录成功!,系统将在'+timeout+'秒后跳回...';}setTimeout('dectime()',1000);}}function dectime(){timeout--;redirect(redirectpage);}redirect('"& Request.ServerVariables("HTTP_REFERER") &"');</script>"
这是用asp写的..net的也一样.稍微改改就行了.
相信你能完成的.
