Thread:Extension talk:MobileFrontend/wgMFAutodetectMobileView and FileCache/reply

Not only are there $wgUseFileCache issues, also maybe the HTTP response headers sent by Mediawiki need to be beefed up, lest someone retrieve some ISP's cached copy somewhere. Or maybe even an &sid=e8d89sd089 URL suffix needs to be added? (All guesses of mine.)
