Web programming: ‘cache-control header is missing or empty’
Self-tutoring about web experimentation: the tutor shares an observation.
In Developer Tools, I get the ‘cache-control header is missing or empty’ when I load a local file, but not one from a server. I’m under the impression that, when that header is absent, the browser reloads stylesheets, images, etc, each time, while it typically would cache them when the header is set. It’s actually useful to have it not, therefore, when experimenting with a stylesheet.
