Imaging following situation:

You have a restricted area with unique content per user and not per user group (-> no Context aware HTTP cache https://doc.ez.no/display/EZP/Context+aware+HTTP+cache )

and some legacy templates. 

A setting the ttl to 0 in legacy templates with {set-block scope=root variable=cache_ttl}0{/set-block} has no effect, you will need to use an alternative. There are two possibilities:

1. Make the user hash whichs controls caching unique, as described in https://doc.ez.no/display/EZP/How+to+customize+UserHash+generation.

This results in mainly useless caches.

2. Mark the response header as private, which prevents caching:

Write an own controller.

https://doc.ez.no/display/EZP/How+to+use+a+custom+controller+to+display+a+content+or+location#Howtouseacustomcontrollertodisplayacontentorlocation-Enrichingbuilt-inViewController

BUT: The example in documentation is only for eZ Symfony results, legacy results will not work!

If you have legacy templates in use, make it like this:

Go into your src/CjwNetwork/SiteCustomerBundle/Resources/config/override.yml and add an matching for your internal area:

system:
    customer_user_de:
        location_view:
            full:
                section_internal:
                    # Configuring both controller and template as the controller will forward
                    # the request to the ViewController which will render the configured template.
                    controller:  "CjwSiteCustomerBundle:Cjw:sectionInternal"
        # you can take this for a eZ Symfony result, not for legacy template results
                    #  template: "CjwSiteCustomerBundle:Cjw:full:legacy.html.twig"
                    match:
                        Identifier\Section: internal

in your src/CjwNetwork/SiteCustomerBundle/Controller/CjwController.php

<?php

namespace CjwNetwork\SiteCustomerBundle\Controller;
use eZ\Bundle\EzPublishCoreBundle\Controller;
use Symfony\Component\HttpFoundation\Response;
use eZ\Publish\API\Repository\Values\Content\Query;
use eZ\Publish\API\Repository\Values\Content\Query\Criterion;
use eZ\Publish\API\Repository\Values\Content\Query\SortClause;
use eZFunctionHandler;



class CjwController extends Controller
{
    /**
     * Sets a new header for private sections
     *
     * @param $locationId
     * @param $viewType
     * @param bool $layout
     * @param array $params
     *
     * @var $kernel  \eZ\Publish\Core\MVC\Legacy\Kernel
     *
     * @return \Symfony\Component\HttpFoundation\Response
     */

    public function sectionInternalAction($locationId, $viewType, $layout = false, array $params = array())
    {


        $response = new Response();
// get the legacy kernel
        $kernel = $this->getLegacyKernel();
// get rid of the pagelayout.tpl
        $kernel->setUsePagelayout(false);
// get the rendered content
        $legacy_content = $kernel->run()->getContent();
// put the rendered content into the twig template and add the locationId for getting breadcrump etc.
        $response = $this->render('CjwSiteCustomerBundle:full:legacy.html.twig', array('legacy_content' => $legacy_content, 'locationId' => $locationId));
// set the header to private,
        $response->setPrivate();
        $response->headers->set('X-Location-Id', $locationId);
        $response->setVary('X-User-Hash');

        return $response;
    }
}

the template full/legacy.html.twig

{% extends 'CjwSiteCustomerBundle::pagelayout.html.twig' %}
 
{% block content %}
 
   {{ legacy_content|raw }}
 
{% endblock %}
