| 使用CDN后，获取真实IP 办法
Supesite使用CDN后获取真实IP 办法 include/main.inc.php文件，这部分 if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {

改为
//showmessage('register_invite_iperror');

}替换成： $onlineip=getenv('HTTP_X_FORWARD_FOR');-------------------- 做了CDN的ASP网站如何取到用户真实IP程序 function checkip(checkstring)'用正则判断IP是否合法
dim re1
set re1=new RegExp
re1.pattern="^[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}$"
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.ServerVariables("HTTP_CLIENT_IP"))=true then
get_cli_ip = checkip(Request.ServerVariables("HTTP_CLIENT_IP"))
else
MyArray = split(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")
end if
end functionASP.NET获取IP的6种方法服务端： //方法一 HttpContext.Current.Request.UserHostAddress; //方法二 HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]; //方法三 string strHostName = System.Net.Dns.GetHostName(); string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue(0).ToString(); //方法四（无视代理） HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; 客户端： //方法五
var ip = '<!--#echo var="REMOTE_ADDR"-->';
alert("Your IP address is "+ip);
//方法六（无视代理）
function GetLocalIPAddress()
{
var obj = null;
var rslt = "";
try
{
obj = new ActiveXObject("rcbdyctl.Setting");
rslt = obj.GetIPAddress;
obj = null;
}
catch(e)
{
//
}
return rslt;
}来自印度的MCT Maulik Patel提供了一种服务端的解决方案，很好： if(Context.Request.ServerVariables["HTTP_VIA"]!=null) // using proxy
{
ip=Context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString(); // Return real client IP.
}
else// not using proxy or can't get the Client IP
{
ip=Context.Request.ServerVariables["REMOTE_ADDR"].ToString(); //While it can't get the Client IP, it will return proxy IP.
}备注：1. 有些代理是不会发给我们真实IP地址的 2. 有些客户端会因为“header_access deny”的安全设置而不发给我们IP
