Manual removing view cache

I built two applications on the Phalcon PHP framework:

• frontend, which is based on Phalcon Website
• and backend, which is based on Vokuro.

In production mode I need to remove view cache for following content after database update from the backend:

• /en/encyklopaedia/
• /en/encyklopaedia/p/
• /en/encyklopaedia/p/payload.html
• /en/tutorials/
• /en/tutorials/setup-in-Debian-9.html

In production mode in /storage/cache/view Phalcon is creating following files for above urls:

• _en_encyklopaedia_.cache
• _en_encyklopaedia_p_payload.html.cache
• _en_encyklopaedia_p_payload.html.cache
• _en_tutorials_.cache
• _en_tutorials_setup-in-Debian-9.html.cache

What is the key to delete them:

$this->getDI()->get('viewCache')->delete($cacheKey)

?

Thanks for your time.
