SilverStripe CDN Integration

Updated on October 4, 2018
SilverStripe CDN Integration

SilverStripe is an open source CMS that prides itself on being easy to use, very extensible, and secure. The CMS was designed to cater to a variety of individuals including developers, marketers, authors, and IT managers. The SilverStripe CMS powers the websites of some very well known brands including:

  • Forbes,
  • Lenovo,
  • Westpac, and more

However, regardless of how to easy to use or flexible a CMS is, performance is one major factor that can almost always be improved upon. That's why in this guide we're going to demonstrate how SilverStripe users can implement a SilverStripe CDN integration to further accelerate the delivery of their static assets.

SilverStripe CDN integration

The following SilverStripe CDN integration guide requires you are using version 3.1.x of either the SilverStripe framework or CMS. Follow each step below to complete the integrate and have your SilverStripe running faster for users globally.

  1. Before starting the integration process, create a Pull Zone in your KeyCDN dashboard.

  2. Install the silverstripe_cdnrewrite module manually or by running the following Composer command.

    composer require wernerkrauss/cdnrewrite dev-master
  3. Open your config.yml file and enable the CDNRewriteRequestFilter filter manually by setting the CDNRewriteRequestFilter.cdn_rewrite and CDNRewriteRequestFilter.cdn_domain config variables.

  4. Your config.yml file should look similar to the following:

        cdn_rewrite: true #global switch
        cdn_domain: ''
        rewrite_assets: true #rewrite stuff in assets
        rewrite_themes: false #do not rewrite stuff in themes folder
  5. Be sure to define the proper protocol and Zone URL or custom CDN domain for the cdn_domain variable.

  6. Save your config.yml file and check the page source for your site to ensure that your static assets have been properly rewritten to use the CDN URL.

That's it! Now you can automatically start accelerating your SilverStripe's static assets using a content delivery network.
