That's what we used to do for CSS/JS--but we don't serve individual files like that anymore--they're all served together via the resource loader. Also, it wouldn't have helped much in this case--the problem was that the HTML/CSS output changed in an incompatible way and we had old (or new, during the rollback) versions of the HTML still being served via Squid (they're cached for 30 days, unless something purges them like an edit). "Don't change the HTML in incompatible ways" is probably a good general rule to live by--but having an easy way to say "start purging all pages on $theseWikis from Squid/Varnish" would also be nice. -Chad _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
