**Problem** The file upload form submit automatically whenever the name of the selected file changes. If the user picks a file, and then navigates back the field is pre-filled because the page is loaded from the browser’s back/forward cache. This means that if they pick the same file again, the value of the upload field hasn’t changed, and the form won’t be submitted. **Solution** The solution is to clear the form field[1] if the page is being loaded from the back/forward cache. Then any time the user picks a file it represents and actual change. 1. http://stackoverflow.com/questions/8861181/clear-all-fields-in-a-form-upon-going-back-with-browser-back-button
