1.首先你的虚拟主机要能支持绑定多个域名
2.在index.asp中放入一段代码用以判断域名和转向到子目录
<%
Dim StrDomain
StrDomain=Request.ServerVariables("SERVER_NAME")
'获得包含域名的字符串
select case StrDomain
case "www.aaa.com"
Response.redirect "http://www.aaa.com/aaa/index.asp"
case "www.bbb.com"
Response.redirect "http://www.bbb.com/bbb/index.asp"
case else
Response.write "未知错误"
end select
%>
