Laurence 'GreenReaper' Parry <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #16 from Laurence 'GreenReaper' Parry <[email protected]> --- I can confirm, the default $wgMediaViewerUseThumbnailGuessing = true doesn't always work right if you don't have a 404 handler set up. Here's why: large sites probably *do* have caching set up (e.g. CloudFlare or Varnish), and the 404 will be cached, so the request after generation gets the cached 404. Whoops. This hurts everyone else who tries to access the cached file while the 404 is cached. You could try adding no-cache headers to your second request; or if that is not possible, add a query parameter to the URL based on, say, the timestamp to break the cache for your backup request. -- You are receiving this mail because: You are the assignee for the bug.
