ECSHOP发现后台频道的退出，频率甚至到了一两分钟就退出，通过以下方法可以解决：
打开 include/lib_base.php
找到 real_ip()函数，在real_ip函数中添加红色部分代码：
将：

function real_ip()
{
static $realip = NULL;

if ($realip !== NULL)
{
return $realip;
}

if (isset($_SERVER))
{
if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
{
$arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);

/* 取X-Forwarded-For中第一个非unknown的有效IP字符串 */
foreach ($arr AS $ip)
{
$ip = trim($ip);

if ($ip != 'unknown')
{
$realip = $ip;

break;
}
}
}
elseif (isset($_SERVER['HTTP_CLIENT_IP']))
{
$realip = $_SERVER['HTTP_CLIENT_IP'];
}
else
{
if (isset($_SERVER['REMOTE_ADDR']))
{
$realip = $_SERVER['REMOTE_ADDR'];
}
else
{
$realip = '0.0.0.0';
}
}
}
else
{
if (getenv('HTTP_X_FORWARDED_FOR'))
{
$realip = getenv('HTTP_X_FORWARDED_FOR');
}
elseif (getenv('HTTP_CLIENT_IP'))
{
$realip = getenv('HTTP_CLIENT_IP');
}
else
{
$realip = getenv('REMOTE_ADDR');
}
}

preg_match("/[\d\.]{7,15}/", $realip, $onlineip);
$realip = !empty($onlineip[0]) ? $onlineip[0] : '0.0.0.0';

return $realip;
}

function real_ip()
{
static $realip = NULL;

if ($realip !== NULL)
{
return $realip;
}
/*添加*/
if(isset($_COOKIE['real_ipd']) && !empty($_COOKIE['real_ipd'])){
$realip = $_COOKIE['real_ipd'];
return $realip;
}
/*添加*/

if (isset($_SERVER))
{
if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
{
$arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);

/* 取X-Forwarded-For中第一个非unknown的有效IP字符串 */
foreach ($arr AS $ip)
{
$ip = trim($ip);

if ($ip != 'unknown')
{
$realip = $ip;

break;
}
}
}
elseif (isset($_SERVER['HTTP_CLIENT_IP']))
{
$realip = $_SERVER['HTTP_CLIENT_IP'];
}
else
{
if (isset($_SERVER['REMOTE_ADDR']))
{
$realip = $_SERVER['REMOTE_ADDR'];
}
else
{
$realip = '0.0.0.0';
}
}
}
else
{
if (getenv('HTTP_X_FORWARDED_FOR'))
{
$realip = getenv('HTTP_X_FORWARDED_FOR');
}
elseif (getenv('HTTP_CLIENT_IP'))
{
$realip = getenv('HTTP_CLIENT_IP');
}
else
{
$realip = getenv('REMOTE_ADDR');
}
}

preg_match("/[\d\.]{7,15}/", $realip, $onlineip);
$realip = !empty($onlineip[0]) ? $onlineip[0] : '0.0.0.0';
/*添加*/ setcookie("real_ipd", $realip, time()+36000, "/"); /*添加*/
return $realip;
}
