- Maintain Your Custom Domain
To keep your custom domain running smoothly, follow these guidelines. If you serve your domain with your HTTPS certificate, update the certificate before it expires. Optimize your domain that uses the Salesforce content delivery network (CDN). Minimize downtime when you update your domain, and take steps to help prevent domain takeover attacks. And review recommendations for communicating to your users when you change your domain. - View Your Custom Domain Details
Get information about your custom domain. For example, scan the expiration dates for your HTTPS certificates that serve your domains. Or get the target host name for your domain that’s served by a third-party service or content delivery network (CDN). Also, you can view and manage the custom URLs associated with the domain, and view alerts about the domain’s DNS configuration. - Redirect System-Managed Site URLs to Your Custom Domain
To reinforce your brand, redirect users that visit a system-managed .my.site.com or .my.salesforce-sites.com URL to the custom domain that serves that site’s content. - Enable HSTS Preloading on a Custom Domain
As a security best practice, enable and submit your custom domain for HTTP Strict Transport Security (HSTS) preloading. Connections can be vulnerable when HTTP requests are redirected to HTTPS. An example is a user attempting to access your custom domain using the HTTP protocol. By adding your registrable domain to the third-party HSTS preload list, supported browsers always use HTTPS, protecting your users from attacks during those HTTP redirections. - Update an Expiring Certificate for Your Custom Domain
If you serve your domain with your HTTPS certificate on Salesforce servers, avoid disruption to your domain by renewing or replacing your certificate before it expires. You can find the expiration date for your HTTPS certificates on the Certificate and Key Management Setup page. Also, admins receive an expiring certificate notification email before the certificate expires. - Change the Domain Configuration Option for Your Custom Domain
Change the method for serving your domain. For example, switch from a third-party service or content delivery network (CDN) to the Salesforce CDN. Update your domain in Salesforce to use a different third-party service or CDN to serve your site. Or update a temporary non-HTTPS domain to use HTTPS as required by Salesforce. - Change the Domain Name for a Custom Domain
Whether your brand changed or you want to use a different domain to serve your site content, you can change the domain name of an existing custom domain in Salesforce. Review these important steps to ensure a smooth transition and reduce the risk of takeover attacks. - Move a Domain to Another Production Org
If you purchase a new production org, your old org continues to serve your sites with your custom domain. To move the domain to your new org, set up the domain, and then delete the domain in your old org. Or if you have multiple production orgs, you can move an existing domain to an org of your choice. - Delete a Domain
To stop serving a site via your custom domain, such as https://www.example.com, first delete the custom URLs for that domain. Then delete the domain in Salesforce. Or to point the domain to a different site, set up new custom URLs.
