I am investigating using a cache manifest. If I have a manifest such as:
CACHE MANIFEST
stylesheets/style.css
And in the page I have a CSS element referencing stylesheets/style.css?v=123.
Will the style.css file be retrieved from the cache or remotely?
The URL in the cache manifest and the URL you’re calling must match (INCLUDING the query).
In your example:
CACHE MANIFEST stylesheets/style.css
in HTML: stylesheets/style.css?v=123
The browser will ALWAYS try to fetch the CSS file from the server, since only the query-less CSS file is cached locally. Use of stylesheets/style.css in cache is sufficient.
