    We have an MVC app with some webapi controllers that use custom security based on a header that the request must include.

    How can we modify the controls to make them include the headers when they request the data to the server?

    As far as we've been seen, we can put the URL they call, but we don't know how to add custom headers.

    Thanks in advance.

    I am assuming you're referring to ajax calls. 

     We do something like this - you should be able to roll your own based on this:

    <script type="text/javascript">

      $("#RootMenu").css({ "background-color": "transparent", "background": "transparent" });

      $(function () {

        // Setup CSRF safety for AJAX:
        $.ajaxPrefilter(function (options, originalOptions, jqXHR) {
          if (options.type.toUpperCase() === "POST") {
            // We need to add the verificationToken to all POSTs
            var token = $("input[name^=__RequestVerificationToken]").first();
            if (!token.length) return;
            var tokenName = token.attr("name");
            // If the data is JSON, then we need to put the token in the QueryString:
            if (options.contentType.indexOf('application/json') === 0) {
              // Add the token to the URL, because we can't add it to the JSON data:
              options.url += ((options.url.indexOf("?") === -1) ? "?" : "&") + token.serialize();
            } else if (typeof === 'string' && === -1) {
              // Append to the data string:
     += ( ? "&" : "") + token.serialize();
          var verificationToken = $("meta[name='__AjaxRequestVerificationToken']").attr('content');
          if (verificationToken) {
            jqXHR.setRequestHeader("X-Request-Verification-Token", verificationToken);

     Again - this is just what we do - but you should be able to run with it..
