Add request header for upload action

Platform: jQuery |
Control: ejUploadbox


To add a request header during upload action in Upload box.


You can add a custom request reader in upload box action during beforeSend event of Uploadbox which will be triggered before file has been sent to the server.

Please refer to the below code:

 <script type="text/javascript">  
        $(function () {  
            // declaration  
                saveUrl: "api/UploadBox",  
                 beforeSend: function (args) {  
                 args.xhr.setRequestHeader("securityToken", "23456");  


public class UploadBoxController : ApiController
        public void Save()
            if (HttpContext.Current.Request.Files.AllKeys.Any())
                var httpPostedFile = HttpContext.Current.Request.Files["Uploadbox"];
                if (httpPostedFile != null)
                    var fileSave = HttpContext.Current.Server.MapPath("UploadedFiles");
                    if (!Directory.Exists(fileSave))
                    var fileSavePath = Path.Combine(fileSave, httpPostedFile.FileName);


You can get the header details from HttpContext.Current.Request.Headers. Security token details can be viewed in network tab as shown in the below image.
