How to use additional domains

On this page

Your Sirv account can serve images from many different domains/subdomains, enabling you to personalize your file URLs however you wish. It's particularly useful for serving images to multiple websites, with each site having its own custom image URLs.

The option to add new domains is available from the Settings page of your account:

Add additional domains

Multiple sirv.com and custom domains

Every domain added to your account will have a direct sirv.com subdomain and a customizable CDN domain.

Your custom domains can be any subdomain of any domain you own e.g.

  • cdn.your-domain.com
  • images.your-other-domain.com

You will receive a free SSL certificate for each custom domain, so files can be served over HTTPS.

To serve files from a subdomain of your own website, add a CNAME record to your domain's DNS record, pointing to the new Sirv subdomain. The full CNAME record would look like this:

cdn.yourwebsite.com. 300 IN CNAME additional-domain.sirv.com.

It may take about 10 minutes for your new DNS settings to propagate around the internet, then setup your custom domain in the additional domain "Details":

Custom folders

The root folder of each of your custom domains can be configured separately. By default, the root folder will be your home Sirv folder. You could change it to any folder or subfolder in your account.

For example, let's say you had a custom domain of cdn.arkwright-furniture.com, you could map that to a folder such as /arkwright in your Sirv account. An image located at /arkwright/example.jpg would be served from cdn.arkwright-furniture.com/example.jpg.

Custom profiles

Each subdomain can have its own Default profile. The Default profile contains the standard settings applied to all your images. A different default profile could be used to apply a watermark to images from a certain subdomain or change the TTL file caching time or any of the other 100+ default settings.

Before setting a different default profile for a subdomain, create a new profile in your Profiles folder, with the custom default settings you wish to have.

Pricing

Additional domains are charged at $5/month.
