How to access previous static resources after deployed a new version?

Support

Hi team,

We find that netlify uses [What are Atomic deploys? Immutable deploys? Learn here!](https://Atomic Deploys) which may introduce a problem that user may got 404 error, if they still access the previous static resources after deployed a new version.

Is there any config that can only update the index.html and retain the previous static resources when deployed ?

Thanks.

The recommended solution for this is the use of a service worker to cache the javascript bundles in the end user’s browser.

This allows the user to keep using the previous version of the page and the service worker will update the bundles when the HTML URL is reloaded.
