If your B2evolution site doesn’t perform well, use CDN. Here are detailed instructions on how to integrate CDN with a B2evolution.

Before you start

  • Before you take any steps please back up your files and database.
  • In the following, we will integrate a CDN service using the CDN domain 12345.r.cdnsun.net. Please visit the Services/How-To section to obtain your CDN domain.
  • To integate a CDN service on https:// website you can use https://12345.r.cdnsun.net or you can use a custom CDN domain with SSL enabled.
  • If your website embeds custom fonts then please first enable CORS for them.
  • Before you take any steps please make sure that your CDN domain is ready-to-use here.

Create CDN Static service

Please refer to Creating a CDN Static service for more details.

Enable CDN in b2evolution

  1. In the b2evolution document root in the file conf/_basic_config.php replace the following:
    $assets_baseurl = $baseurl;    
    with the following:
    $assets_baseurl = 'http://12345.r.cdnsun.net/';            
  2. That's all.


  • View HTML source code of your web pages to verify that you are using CDN, you should see source attribute of your images, CSS, JavaScript, etc. beginning with your CDN domain.
  • Don't see your CDN domain in source code of your web pages? If your website is using any cache plug-in/mechanism then you might want to clear/flush its cache.
