Remove Instance Names from URLs for Visualforce, Community Builder, Site.com Studio, and Content Files (Critical Update)
|Available in: Salesforce Classic and Lightning Experience|
|Available in: Contact Manager, Group, Professional, Enterprise, Performance, Unlimited, and Developer Editions|
Prior to Winter ’18, Visualforce, Community Builder, Site.com Studio, and content file URLs included the instance name of the org, even when a My Domain name was deployed. An instance name identifies where your Salesforce org is hosted.
When we remove the instance name from your URLs, your hostnames change.
- mydomain--c.visualforce.com replaces mydomain--c.na1.visual.force.com
- mydomain--c.documentforce.com replaces mydomain--c.na1.content.force.com
After this update, a URL that includes the instance name, such as a bookmark, automatically redirects to the new hostname.
This update might log out users who are accessing Visualforce, Community Builder, Site.com Studio, and content file URLs. To minimize disruption, consider activating this critical update during off-peak hours.
