--- Comment #15 from Brad Jorsch <[email protected]> --- (In reply to comment #13) > How is it possible that Firefox' hard reload has another effect on wiki > servers than the one of other browsers? > An empty cache (I mean really deleted, with an entirely new profile) loads a > page the same way like a hard reload, I assume. A normal page load is likely to send headers that allow intermediate caches to return a cached version of the page, while a hard reload will probably include headers that instruct intermediate caches not to cache. In both Firefox and Chromium here a normal page load doesn't send any "Cache-Control" or "Pragma" headers, a normal reload (F5) sends "Cache-Control: max-age=0" (but no "Pragma"), and a hard reload (Ctrl+F5) sends both "Cache-Control: no-cache" and "Pragma: no-cache". Opera 16 seems to do the same thing. On the other hand, IE 9 and 10 and Opera 12 seem to send a "Cache-Control: no-cache" with no "Pragma" header on any reload (both F5 and Ctrl+F5). I don't know whether that's actually the reason, but it's certainly plausible that Wikimedia's caching layer was only revalidating in response to "Pragma: no-cache" and not "Cache-Control: no-cache". -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ Wikibugs-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikibugs-l
