Media Force Refresh Setting

When configuring a Media Resource, you'll have the option to enable Autorefresh. This setting periodically refreshes the image at the interval you set.

By default, the Force Refresh setting is enabled, which initiates a feature commonly referred to as 'cache busting'. During the refresh interval, a unique ID is added to the URL, forcing both the browser and the media source to treat it as a new resource being requested.

Note that many resources require the Force Refresh option to be enabled for proper autorefresh. Without it, the media source or your browser might serve the previous image from memory even with refresh requests. Media sources that include 'no-cache' headers may autorefresh properly with the Force Refresh option disabled. These resources usually refresh correctly even with the setting enabled, so you should generally keep the setting enabled.

There's a small subset of media sources that will only properly refresh with the Force Refresh setting disabled, which is what the setting is intended for.

Additionally, there's another subset of media sources that may not support autorefresh at all. If the media source neither accepts 'cache busting' parameters nor sends the proper 'no-cache' headers, that source will not autorefresh.
