应该把参数如文件名，文件路径传到一个下面这个页面
在这个页面里你对文件名和路径做下更改就能不让用户看到路径了。
下面这个代码你看下。
你只要传递这个参数FileName = Request.QueryString("FileName")进来就OK了。
路径下面你可以设置，也可以自己传进来。呵这个挺好用的。
<%
From_url = Cstr(Request.ServerVariables("HTTP_REFERER"))
Serv_url = Cstr(Request.ServerVariables("SERVER_NAME"))
if mid(From_url,8,len(Serv_url)) <> Serv_url then
response.write "非法链接！" '防止盗链
response.end
end if
