OpenCart Medianova CDN Integration

Medianova Turkey’s largest e-commerce companies to provide CDN services

In this article, we explained how to integrate Medianova CDN with OpenCart’s 3.x version to our customers who build e-commerce sites on OpenCart platform.

This allows you to get better site performance by serving your static content from the nearest Medianova servers.

1. First, create a Medianova CDN Zone for your content by logging into panel.medianova.com. With this integration, you will be able to serve your small files from Medianova CDN.
2. Download the VQmod plugin from the OpenCart market and follow the installation steps for the OpenCart 3.x version
3. Insert the following XML file into the system/folder. The filename must end with a .vqmod.xml extension. For example cdn.vqmod.xml
