title: jQuery-File-Upload by blueimp - additional headers
body: <p>I've searched through <a href="https://github.com/blueimp/jQuery-File-Upload/wiki" rel="noreferrer">wiki</a> but couldn't find an answer where should I put my additional headers (for example <code>Authorization</code> header) in JS script? Somewhere <code>onSend</code>/<code>beforeSend</code> or?</p>
