An application uses the latest version of jQuery File Uploader and sometimes 499 errors (client closed request) are observed during uploads. My assumption is that this error appears if users are using unstable WLAN connections. Does anybody have experience with this issue and is there a fix for this? I’d like to extend the jQuery File Uploader in order to detect the 499 errors and re-upload the same image again until it goes through. Thanks!

blueimp’s jQuery-File-Upload plugin worked just fine. My app didn’t have to use the original file name for uploading files. Now it is required that the original file name also gets uploaded and stored correctly in the web app.
