Save initial files into cache storage instead of browser's cache

[lewispham]

At this time, there is no way to save intial files which are fetched at the very first HTTP request into CacheStorage. I'm thinking about having a header that handles this issue.

Cache-Control : location=cache-storage

Then developers can easily retrieve those files saved in cache storage on client side.

CacheStrorage.open('main').then(cache => {
    cache.match('/path/to/initFile').then(response => {
        console.log('File exists in cache storage');
    });
});

Is this intended for the initial html request?

@jakearchibald Yes. The initial html request and its following ones.

This issue is actually for getting rid of browser cache. I think having 2 layers of cache is quite hard to manage. Besides this one, there is also another problem with http2 requests. Developers are currently unable to directly save pushed files into CacheStorage. This is also the reason behind my suggestion of using this header Cache-Control : location=cache-storage.
