Question

1C-Bitrix

Hello.
Composite was included on the site. The task was to make a mobile version. I created a new template, implemented a mob in it. version. In the site settings, I specified that the mobile template should be loaded using the PHP expression siteType=='pda' .
init.php

require_once($_SERVER["DOCUMENT_ROOT"]."/include/Mobile_Detect.php");
$detect = new Mobile_Detect();
$flag = $detect->isMobile();
if (strpos($APPLICATION->GetCurDir(), '/product/')!== false || strpos($APPLICATION->GetCurDir(), '/catalog/')!== false || $APPLICATION->GetCurPage(false) === '/') {
    if (!$detect->isMobile()) {
        setcookie('siteType', '', time()+3600*24*30,'/');
        define('siteType','');
        setcookie("MOBILE_VISITOR_MB", "", time()-1000);
    } else {
        if (isset ($_GET['type'])){
            switch ($_GET['type']) {
                case 'pda':
                    setcookie('siteType', 'pda', time()+3600*24*30,'/');
                    define('siteType','pda');
                    break;
                default:
                    setcookie('siteType', '', time()+3600*24*30,'/');
                    setcookie("MOBILE_VISITOR_MB", "", time()-1000);
                    define('siteType','original');
            }
        }
        else{
            $checkType='';
            if (isset($_COOKIE['siteType'])) $checkType=$_COOKIE['siteType'];
            switch ($checkType) {
                case 'pda':
                    define('siteType','pda');
                    break;
                default:
                    define('siteType','');
                    setcookie("MOBILE_VISITOR_MB", "", time()-1000);
            }
        }
    }
} else {
    define('siteType','');
    setcookie("MOBILE_VISITOR_MB", "", time()-1000);
}

header.php of the main template

require_once($_SERVER["DOCUMENT_ROOT"]."/include/Mobile_Detect.php");
    $detect = new Mobile_Detect();
    $flag = $detect->isMobile();
    if (strpos($APPLICATION->GetCurDir(), '/product/')!== false || strpos($APPLICATION->GetCurDir(), '/catalog/')!== false || $APPLICATION->GetCurPage(false) === '/') {
        $VISITOR_ID = $APPLICATION->get_cookie("MOBILE_VISITOR_MB");
        if (($detect->isMobile()) && empty($VISITOR_ID)) {
            $APPLICATION->set_cookie("MOBILE_VISITOR_MB", "MOBILE", time() + 60 * 60);
            LocalRedirect("https://".$_SERVER["SERVER_NAME"] . $_SERVER["REDIRECT_URL"] . "?type=pda");
            exit();
        }
    }

header.php of the mobile template

require_once($_SERVER["DOCUMENT_ROOT"]."/include/Mobile_Detect.php");
        $detect = new Mobile_Detect();
        $flag = $detect->isMobile();
        if (strpos($APPLICATION->GetCurDir(), '/product/')!== false || strpos($APPLICATION->GetCurDir(), '/catalog/')!== false || $APPLICATION->GetCurPage(false) === '/') {
            if (!$detect->isMobile()) {
                $APPLICATION->set_cookie("MOBILE_VISITOR_MB", "", time() - 60 * 60);
                LocalRedirect("https://".$_SERVER["SERVER_NAME"] . $_SERVER["REDIRECT_URL"] . "?type=original");
                exit();
            }
        }

When the composite is off, everything works correctly. Versions are correct. But once you turn on the composite, everything breaks down. The desktop version can be shown on the mobile phone, and the mobile version on the desktop. As I understand it, this is due to the fact that the composite takes data from the cache and it turns out that the check for the device type is ignored. The latest version of the page in the cache is taken. Is it possible to somehow use template substitution and composite?

Did you try to connect all the necessary scripts for this at the init.php level, before the start of the Bitrix layers?
