Users trying to view a breakdown of the API timing for each resource within a browser snapshot may see the following error and be unable to view information on cross-origin resource domains:
The solution for this issue is to allow timing information to be collected from your CDN or other domain. Add the Timing-Allow-Origin header to all requests served by the CDN in your app code.
The value of the header can either be *
(allow timing from requests from any domain) or a list of domains within quotations with spaces separating each one.
Example:
"Timing-Allow-Origin" "*" "Timing-Allow-Origin" "http://foo.com http://bar.com"
After the header has been added to the app code, users should be able to see the breakdown of the timing information within a browser snapshot.
Example:
If the problem persists, capture a HAR file and verify if the header is seen in the response. If not, the header may be stripped off by a proxy or other hardware.
Example:
Header set for Adrum.js resource
