Varnish Cache is an open-source reverse HTTP proxy that can speed up a website by up to 1000%, by caching (or storing) a copy of a webpage the first time a user visits. Varnish Cache 6.0.7 is the latest LTS release.
In addition to the package installation, the One-Click also:
1- Enables the UFW firewall to allow only SSH (port 22, rate limited), HTTP (port 80), and HTTPS (port 443) access.
2- Sets Varnish to answer on port 80 and 8443
3- Set Hitch to answer port 443 and forward request to varnish on port 8443
4- Add a welcome page you can see when visiting the VM’s IP address in your browser.
After you create a Varnish One-Click VM:
1- You can log into the VM as root using either the password emailed to you or with an SSH key if you added one during creation.
2- Get more help on the welcome page by visiting the VM’s IP address in your browser.
