ASP script返回时怎么刷新，请帮忙

ASP script返回时如何刷新，请帮忙！
response.Write   " <script   language=javascript> history.go(-1); </script> "
就这段代码，如何让它返回上一页面后自动刷新一下？

[解决办法]
URL = Request.ServerVariables( "HTTP_REFERER ")

response.Write " <script language=javascript> window.location.href= ' "& URL & " '; </script> "
