Using Varnish cache

<!DOCTYPE html>

# Using Varnish cache

You can now set up Varnish cache for your Magento site through the Nimbus Hosting platform. Varnish is supported on our platform for our Oxygen package and higher and for sites running Magento 2.4 and newer.

**Steps**

1. Once you have Magento 2.4 installed, you'll firstly need to configure Magento to use Varnish as the full page cache. To do this log into your Magento admin area and go to *Stores > Settings > Configuration > Advanced > System > Full Page Cache*
2. Then select Varnish Caching from the caching application list.
3. Next, navigate to the sites configuration page and toggle on the Varnish option.\

4. If all goes smoothly then the sites will start loading through Varnish. If you find it’s not worked and you see a message such as “503 backend fetch failed” then simply un-toggle the Varnish button in the platform and it will revert back to normal.
5. You can confirm that requests are going through Varnish by logging onto the server via SSH and running the "varnishlog" command.

**Using a custom VCL file**

When you enable Varnish from within the hosting app, we provide a default VCL file that's ready optimised for working on our servers. However, you may wish to use a custom VCL file instead of the one we provide.

To export your site's custom VCL file navigate to the Magento 2 admin dashboard and export the site's Varnish config file. This can be found in:.  

*Stores> Configuration> Advanced> System> Full Page Cache> Varnish Caching> Export VCL for Varnish 6*

Once you have the file, you will then need to upload this to the server and place it in the following location:

/etc/varnish/default.vcl

Then restart Varnish to activate the new configuration.

**Summary**
