function checkip(checkstring)'用正则判断IP
是否合法
dim re1
set re1=new RegE
xp re1.pattern="^[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}$"
re1.global=false
re1.Ignorecase=false
checkip=re1.
test(checkstring)
set re1=nothing
end function
function get_cli_ip()'取
真实ip函数,先 HTTP_CLIENT_IP 再 HTTP_X_FORWARDED_FOR 再 REMOTE_ADDR
dim client_ip
if checkip(Request.Server
VARiables("HTTP_CLIENT_IP"))=true then

IT(Request.ServerVariables("HTTP_X_FORWARDED_FOR"),",")
if
ubound(MyArray)>=0 then
client_ip = trim(MyArray(0))
if checkip(client_ip)=true then
get_cli_ip = client_ip
exit function
end if
end if
get_cli_ip = Request.ServerVariables("REMOTE_ADDR")
