Chrome 91 Update : Guide to Cross-Origin Isolation

Chrome 91 Update : Guide to Cross-Origin Isolation

As part of the Chrome 91 update on the 25th May 2021, functionalities that use SharedArrayBuffer will no longer work without cross-origin isolation.

In response to this, Publift has updated our CDN to be compliant with the COOP/COEP requirement by serving FUSE scripts with an additional HTTP header - "cross-origin-resource-policy" with the value "cross-origin".

However, if your site is currently using any related core browser features like SharedArrayBuffer, it is highly recommended to check if any of the browser methods used are related to COOP/COEP, as these have the potential to break your site due to depreciation. To ensure that your site complies with the upcoming update, please implement any required changes by following the steps in this link.

Should you have any questions or require further assistance, please contact support@publift.com.
