asp的两个应用外部提交和判断ip

server_v1=cstr(request.servervariables(“http_referer”))
server_v2=cstr(request.servervariables(“server_name”))
if mid(server_v1,8,len(server_v2))<>server_v2 then
response.redirect “index.asp”
end if
userip = Request.ServerVariables(“HTTP_X_FORWARDED_FOR”)
If userip = “” Then userip = Request.ServerVariables(“REMOTE_ADDR”)
if userip=”219.118.84.49″ then response.redirect “index.asp”
