jQuery Ajax发布禁止

I've a problem with a simple ajax post by jquery:

$.ajax({
  type: 'POST',
  url: "ucUploadDownloadCommand.ascx/UploadXLSFile",
  data: "{}",
  dataType: 'json',
  contentType: "application/json; charset=utf-8",
  success: function (response) {
       $(".im").css('visibility', 'hidden');
  },
  error: function(xhr, textStatus, error){
          alert(xhr.statusText);
          alert(textStatus);
          alert(error);
  }

and in code behind (file ucUploadDownloadCommand.ascx.vb):

<System.Web.Services.WebMethod()> _
    Public Shared Sub UploadXLSFile()
        Dim a As New StringBuilder()
        ...
    End Sub

but it goes wrong with

"Forbidden" error (no "not found" one)

. How can I solve this problem?

Thanks in advance.
