What does a status code of 0 mean? Does it mean the same thing across all browsers, and for all HTTP client utilities? Is it part of the HTTP spec or is it part of some other protocol spec? It seems to mean that the
Http Error 0 Ajax
HTTP request could not be made at all, perhaps because the server address could not be resolved. What error message is appropriate to show the user? "Either you are not connected to the internet, or the website is encountering problems, or there might be a typing error in the address"? I should add to this that I see the behavior in FireFox when set to "Work Offline", but not in Microsoft Internet Explorer when set to "Work Offline". In IE, the user gets a dialog giving the option to go online. FireFox does not notify the user before returning the error. I am asking this in response to a request to "show a better error message". What Internet Explorer does is good. It tells the user what is causing the problem and gives them the option to fix it. In order to give an equivalent UX with FireFox I need to infer the cause of the problem and inform the user. So what in total can I infer from Status 0? Does it have a universal meaning or does it tell me nothing? ajax browser xmlhttprequest share|improve this question edited Oct 19 '14 at 15:02 Mark Amery 23.4k12118147 asked Sep 29 '10 at 20:28 Mark Lutton 3,62632842 Please see this question, which covers the same topic: stackoverflow.com/questions/872206/… –Scott Stafford Sep 29 '10 at 20:29 2 I believe this is the most accurate an

So if you try to connect to "www.google.com/lksdfk" you will get a return code of 400, if you go directly to google.com, you will get 302 (and then 200 if you forward to the next page... well I do because it forwards to google.com.br, so you might not get that), and if you go to "googlecom" you will get a 0 (host no found), so with the last one, there is nobody to send a code back. Tested using the code below. $html_brand, CURLOPT_RETURNTRANSFER => true, CURLOPT_HEADER => true, CURLOPT_FOLLOWLOCATION => true, CURLOPT_ENCODING => "", CURLOPT_AUTOREFERER => true, CURLOPT_CONNECTTIMEOUT => 120, CURLOPT_TIMEOUT => 120, CURLOPT_MAXREDIRS => 10, ); curl_setopt_array( $ch, $options ); $response = curl_exec($ch); $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE); if ( $

This tiny patch changes the wording to give appropriate information so that in the future perhaps a few of these can be resolved. What happens: There are literally dozens of open issues that say "HTTP error 0 occurred". However, there are few of these that get resolved because this information is completely inadequate and usually results http error 0 from an aborted AJAX request, so it's completely invisible. What I expect: The popup should at least provide the available information so the issue can (perhaps) be debugged. What happens instead: Nothing but a dialog box that says "HTTP Error 0 occurred".
