Issue
Customers may encounter issues when attempting to use an iFrame on an external website to open ServiceNow pages.
Release
Utah and later
Cause
In earlier versions, loading a ServiceNow page from an external site was not supported due to different origin restrictions. However, starting with the Utah release, this limitation has been addressed by allowing modifications to the HTTP Header Response.
Resolution
With the Utah release, it is now possible to modify the HTTP Header Response to enable embedding ServiceNow pages using iFrames on external websites. This can be configured to allow the page to be loaded from a different origin, resolving the previous issue.
