As it currently stands, Magento 2 flushes the Varnish cache by performing a HTTP PURGE request.
This makes Magento 2 and Varnish unsuitable for use on a shared hosting environment where every user has their own Varnish instance, since everyone can connect to this port and thus flush the cache of every other user.
In Magento 1 (with the Turpentine extension), the cache is flushed through the management interface and protected by the shared secret.
Are there any plans to develop 'Magento-1-style' cache flushes and disallow flushing through the HTTP port?
