Resources that should be cached (stylesheets, images) but change at unexpected times are indeed a problem.A well understood approach is to push some kind of version indicator into the URI (such as query parameter).
Yeah, I was wondering why that was not acceptable here. (Using /script?v=1 etc. where /script?v=x has near-infinite caching.)
