I store static web-page with index.html file and related resources (js, css etc.) in the feed. After uploading a new version of the site, my users don't see it until they hard refresh page with cache cleaning in browser. I suppose, there is a bug in your cache-control response headers. It returns "cache-control: max-age=2147483648, immutable" header, but files in a feed are mutable.

Expected behaviour

Files in a feed must not be cached in browsers. The gateway doesn't return caching HTTP-headers for files in a feed.

Actual behaviour

The gateway returns "cache-control: max-age=2147483648, immutable" header for files in a feed.

Steps to reproduce the behaviour

Open any feed URL. I work with this:
