Make Img_Auth.php configurable to enable/disable client media caching
Open, Needs TriagePublicFeature


Local caching of uploaded media by the client is normally behavior in mediawiki, but small organizations using MediaWiki to distribute official documents need to ensure that Mediawiki always provides the latest version of an uploaded file.

Not wanting to change the default behavior, but it would be nice if there was a configuration variable in LocalSettings.php that determined whether or not the wiki forces clients get a fresh copy of a file that they already have in cache.
