asp怎么调用本页的url？？
request.ServerVariables("script_name")
用这个就可以，或者
'获取本页地址
Function GetUrl()
  On Error Resume Next
  Dim strTemp
 If LCase(Request.ServerVariables("HTTPS")) = "off" Then
  strTemp = "http://"
 Else
  strTemp = "https://"
  End If
  strTemp = strTemp & Request.ServerVariables("SERVER_NAME")
  If Request.ServerVariables("SERVER_PORT") <> 80 Then strTemp = strTemp & ":" & Request.ServerVariables("SERVER_PORT")
  strTemp = strTemp & Request.ServerVariables("URL")
  If Trim(Request.QueryString) <> "" Then strTemp = strTemp & "?" & Trim(Request.QueryString)
  GetUrl = strTemp
End Function
判断的话可以这样
url=replace(geturl(),"http://","")
cdj=split(url,"/",-1)
cd=cdj(0)
if cd="www.163.com" then
response..Redirect("网址")
elseif cd="...." then
...
end if
