Cache Headers Feature

Sets the inclusions, exclusions and lifetime of HTTP cache headers

If code is edited in the IDE that affects the front-end, you must use the Cache Headers feature to reset the cache key for those changes to reflect in the User Interface (UI). Only administrators have permissions to do this.

The feature may not be enabled in situations where a performance benefit at the expense of file caching may be not be desired, for example, a VNEXT environment.

If the changes made in the IDE affecting the UI are not reflected, it is likely that the cache headers have not been reset.

Access the Cache Headers Feature by navigating to: System Administration > Integrations > Global Features, then search for cache headers.
