I cannot find this in the documentation. I also did a run through the jquery source and can't find any more info.
By using jquery.ajax, when can I expect the fail callback to be run?
Apart of the following:
server is down and does not respond
// EDIT: added after comments, a lot of thanks to @charlietfl :
http error code equal to or greater then 400
what are the other cases when jquery will run the fail callback?
When the response status returned is 4xx or 5xx, which indicates a client-side or server-side error respectively. Here's the entire list of such status codes.
