Repros in Chrome 2.0.172.30 and Safari 4 beta. Does NOT repro in SF 3, Chrome 1, FF2-3, IE7. Test case: http://uwtools.com/sf4cache/bug.html Setup: 1. On load, bug.html appends "js.php" as a script element. 2. js.php issues redirect to public.php: Cache-Control: no-cache, no-store, must-revalidate, max-age=0 Pragma: no-cache Location: http://www.uwtools.com/sf4cache/public.php 3. public.php contains a js file with headers: Cache-Control: public Last-Modified: Mon, 23 Mar 2009 22:26:16 GMT Expected Result: Reloading bug.html should reload js.php due to the no-cache headers of js.php (e.g., to get a new redirect location). Actual Result: Reloading bug.html does not load js.php.
I doubt that this is a WebKit issue, although the fact that it fails in both Chrome in Safari suggests that it might be.
