Redirect b-cdn.net to Custom Hostname

Use Edge Rules to redirect your default b-cdn.net hostname to your custom CDN hostname.

Edge Rules allow you to redirect your default b-cdn.net hostname to your custom hostname, ensuring your content is only accessible through your own domain.

This is useful for:

• SEO purposes (avoiding duplicate content)
• Brand consistency
• Ensuring all traffic goes through your custom domain

Prerequisites

• A pull zone with a custom hostname already configured
• The custom hostname should have SSL enabled

Configuration

1. Open Edge Rules

   Navigate to your pull zone and select Edge Rules from the side menu.

2. Add a new rule

   Click Add Edge Rule to open the rule configuration page.

3. Configure the redirect action

   Select Redirect To URL as the action.

   In the Redirect URL field, enter your custom URL with the {{path}} variable appended:

   https://cdn.yourdomain.com{{path}}
   

   The {{path}} variable automatically includes the full request path and query string, ensuring all URLs redirect correctly.

   Set the status code to 301 for a permanent redirect, or 302 for a temporary redirect.

4. Add a trigger condition

   Click Add Condition and configure:

   Setting	Value
   Condition Type	Request URL
   Match Type	Match Any
   Condition Value	*://yourzone.b-cdn.net/*

   Replace yourzone with the name of your pull zone.

   Make sure to include both the scheme wildcard (*://) and the trailing wildcard (/*) to match all requests to your b-cdn.net hostname.

5. Save the rule

   Click Save Edge Rule to activate the redirect.

Example configuration

For a pull zone named mycdn with a custom hostname cdn.example.com:

Setting	Value
Action	Redirect To URL
Redirect URL	https://cdn.example.com{{path}}
Status Code	301
Condition Type	Request URL
Condition Value	*://mycdn.b-cdn.net/*

Before and after

Original URL	Redirected URL
https://mycdn.b-cdn.net/images/logo.png	https://cdn.example.com/images/logo.png
https://mycdn.b-cdn.net/video.mp4?quality=high	https://cdn.example.com/video.mp4?quality=high
https://mycdn.b-cdn.net/	https://cdn.example.com/

HTTP vs HTTPS

Make sure to use the correct scheme in your redirect URL:

• Use https:// if your custom hostname has SSL enabled (recommended)
• Use http:// only if SSL is not configured

Using the wrong scheme may cause redirect loops or connection errors.
