How to pass data in the ajax DELETE request other than headers

Read this Bug Issue: http://bugs.jquery.com/ticket/11586

Quoting the RFC 2616 Fielding

The DELETE method requests that the origin server delete the resource identified by the Request-URI.

So you need to pass the data in the URI

$.ajax({
    url: urlCall + '?' + $.param({"Id": Id, "bolDeleteReq" : bolDeleteReq}),
    type: 'DELETE',
    success: callback || $.noop,
    error: errorCallback || $.noop
});

I was able to successfully pass through the data attribute in the ajax method. Here is my code

$.ajax({
     url: "/api/Gigs/Cancel",
     type: "DELETE",
     data: {
             "GigId": link.attr('data-gig-id')
           }

  })

The link.attr method simply returned the value of 'data-gig-id' .
