Add support for Nginx + Varnish cache

Hello I'm a new user and I love sPanel and Scala Hosting support team but...

for certain projects we would like to have a level of cache customization that other systems do not allow... Example: for an editorial site we would like the articles to always be served in cache and that the regeneration happens in the background. It seems that varnish is the only system to do it well.

Would it be great to be able to opt for this option, nginx + Varnish, continue to use sPanel and receive your precious real 24/7 assistance to help us configure everything in the best way?

Thanks
Vincenzo
