在ASP.NET MVC 2中上传Http文件

Question

I have simple http form to upload file using http input tag as below:

<% using (Html.BeginForm("Add", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
   {%>
     <label for="file"> Select File :</label>
     <input type="file" name="uploadedFile" value="" accept="text/plain" class="fileUpload" />
     <input id="btnAdd" type="submit" class="button" name="Add" value=" Add "/>
<% } %>

and back in controller I have a corresponding Action:

[HttpPost]
public ActionResult Add(HttpPostedFileBase uploadedFile)
{
    Logger.Debug("Inside Add");

    ProductModel model = new ProductModel();

    if (uploadedFile.ContentLength > 0)
    {
        string filePath = Path.Combine(HttpContext.Server.MapPath("~/Uploads"),
                                       Path.GetFileName(uploadedFile.FileName));
        Logger.Debug("File saved at - " + filePath);
        uploadedFile.SaveAs(filePath);
        model.FileName = uploadedFile.FileName;
        model.Add(filePath);
        return View("Result", model);
    }
    return RedirectToAction("Index");
}

On my development machine and on lab server, this works perfectly. But on production it does not even send any request for submit button. I inspected requests through fiddler, it does not show any traces that request is even originating for this form, from IE 8 on win 2008 r2 production server.

I'm clueless here. What could be the issue? Do you think IE security permissions, UAC, group policies might be an issue? or you have something else to say.

try changing the name of the file input from uploadFile to UploadedFile in the View

<% using (Html.BeginForm("Add", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
   {%>
     <label for="file"> Select File :</label>
     <input type="file" name="UploadedFile" value="" accept="text/plain" class="fileUpload" />
     <input id="btnAdd" type="submit" class="button" name="Add" value=" Add "/>
<% } %>
