21585 2008-10-13 20:11:18 -0700 XMLHttpRequest status code is zero for time-consuming POST request 2008-10-16 02:16:13 -0700 1 1 1 Unclassified WebKit WebCore JavaScript 525.x (Safari 3.1) Mac (Intel) OS X 10.5 RESOLVED DUPLICATE 19758 P3 Normal --- 0 alexcheng1982 webkit-unassigned ap oldest_to_newest 95242 0 alexcheng1982 2008-10-13 20:11:18 -0700 I used a HTTP POST request to fetch data from the server-side. Once the processing time in the server-side is long, say 4 mins, I got a xhr error in the browser side with status code is zero. I tried dojo and jQuery's xhr library. Both have the same problem. I'm wondering if there exists a hidden timeout setting in WebKit. 95243 1 24335 alexcheng1982 2008-10-13 20:12:52 -0700 Created attachment 24335 The source code of my testing servlet 95244 2 24336 alexcheng1982 2008-10-13 20:15:30 -0700 Created attachment 24336 HTML file to test the servlet 95245 3 alexcheng1982 2008-10-13 20:16:05 -0700 Add two attachments of my test 95515 4 ap 2008-10-16 00:53:57 -0700 Does this still happen for you with recent nightly builds from <http://nightly.webkit.org>? 95517 5 alexcheng1982 2008-10-16 01:09:32 -0700 I tried the recent daily build (version 528.5+). It doesn't has the problem. 95518 6 alexcheng1982 2008-10-16 01:30:49 -0700 But WebKit(version 525.x) is shipped with Safari 3.1, which is one of the target browsers of my application. I can not reduce the processing time in the server-side. I also tried to use PUT instead of POST, the same problem occurred. But the GET method is OK. Could you please suggest some workarounds for me to support Safari 3.1? It seems that I can only change the HTTP method from POST to GET. BTW: Safari 3.1 on Windows and Firefox 3 on Mac don't have this problem. 95525 7 ap 2008-10-16 02:16:13 -0700 For a workaround, dummy keep-alive responses can be sent from the server. This will help with proxies closing connections because of timeout, too. *** This bug has been marked as a duplicate of 19758 *** 24335 2008-10-13 20:12:52 -0700 2008-10-13 20:12:52 -0700 The source
