Лак: кешированные и не кешированные субдомены

У нас есть сайт Plone, проходящий через кеш-интерфейс Varnish. Мы хотели бы предоставить два разных субдомена www.site.com и editors.site.com для этого сайта. Последний всегда будет обслуживать не кэшированные версии страниц и использоваться сопровождающими сайта для обновления контента.

Какой самый простой способ сделать это?

Varnish 2.x - на основе шаблона Debian по умолчанию

Конфиг ниже:

 backend default {
     .host = "127.0.0.1";
     .port = "8080";
 }

sub vcl_recv {
    if (req.http.host ~ "(www\.)?site\.com(:[0-9]+)?$") {
                set req.url = "/VirtualHostBase/http/www.site.com:80/LS/VirtualHostRoot" req.url;
                set req.backend = default;      
    }
        else if (req.http.host ~ "editors.site.com(:[0-9]+)?$") {
                set req.url = "/VirtualHostBase/http/editors.site.com:80/LS/VirtualHostRoot" req.url;
                set req.backend = default;
        }
}
