The JetRails extension for Varnish® is a powerful tool that enables developers and Magento 2 site maintainers to manage Varnish Cache™ in a more effective manner. This extension supports both Magento 2 Open Source (CE) and Magento 2 Commerce (EE). This module supports environments with multiple Varnish servers configured. Features include strategies for purging all cache, specific URLs, based on Magento Cache-Tags, and even the ability to interface with Varnish directly and supply a custom rule. Varnish Cache™ can bypass certain pages from being cached by setting rules based on URL path, Magento's route/module/controller/action, wildcard patterns, and RegExp patterns. Additionally, verbose HTTP response headers can be turned on to debug your store's Varnish configuration whilst it is in development.

The MageRepo composer repository allows composer to resolve private packages that JetRails® offers our customers. This process is made easy with the composer CLI tool. This article walks the reader through adding the MageRepo repository via composer or manually adding it into the composer.json file. It then walks through installing and updating a Magento extension through composer.
