There's no preferred/suggested MW way for extensions to cache the stuff they generate. For example, EasyTimeline writes the generated images into $wgUploadDirectory."/timeline/", and there's also $wgCacheDirectory...
For small data, they should use $wgMemc, so this is about having some standard for extension cache files...
(In reply to comment #1) > For small data, they should use $wgMemc, so this is about having some standard > for extension cache files... I believe this is more about things that need to be embedded in the wiki page like math images, timelines, music scores, etc.
CCing Sam just in case there has been any discussion about this. I couldn't find any guidelines in the developer documentation.
