    I am trying to upload a file via a service that implements OData. I cannot seem to set any additional headers on the upload control. I need to set a custom slug header.

    Here is the error I am receiving. Despite what it says the header format is below the error.

    Invalid slug header for attachment. Slug headers must be of the form "EntitySet,ItemId,Name".

    Here is how the headers should look:
        Slug: MyListTitle|1|mydocument.docx

    The latest version of the Upload supplies a reference to the XMLHttpRequest in the upload event.
    This will work only in non-IE browsers, as we use an IFRAME as a fallback in IE.

            function(e) {
              var xhr = e.XMLHttpRequest;
              if (xhr) {
                xhr.addEventListener("readystatechange", function(e) {
                  if (xhr.readyState === 1 /* OPENED */) {
                    xhr.setRequestHeader("Slug", "MyListTitle|1|mydocument.docx");

    I hope this helps.
