Javascript access forbidden on server

Question

I am really stuck with this one, my code works fine on Localhost but not on Fasthosts server, it would appear to be some kind of access problem to a folder on the server, here are the debug messages.

GET (http://reggarockaboogie.co.uk/images/gallery/fld01/) 403 (Forbidden)

k.cors.a.crossDomain.send @ jquery.min.js:4
n.extend.ajax             @ jquery.min.js:4

Here is my code,

     < script >
      $(document).ready(function() {
        LoadGallery($('a[data-albumid]:first').data('albumid'));
        $("a").click(function() {
          var dir_path = $(this).data("albumid");
          LoadGallery(dir_path);
          return false;
        });
      });

    function LoadGallery(dir_path) {
      $.ajax({
        url: dir_path,
        success: function(data) {

          $(".image-container").empty();

          $(data).find("a:contains(.jpg), a:contains(.png), a:contains(.jpeg)").each(function() {
            this.href.replace(window.location.host, "").replace("http:///", "");
            var file = dir_path + $(this).text();
            $(".image-container").append($("<a href='javascript:;' class='thumb' data-src='" + file + "'><img src='" + file + "' title='Click to        enlarge' alt='#'/></a>"));

            if ($(".image-container").children("a").length === 30) {
              return false;
            }
          });

          $(".image-container").append("<strong><p>Click on a thumb nail to show a larger image.</p></strong>");

          $(".thumb").bind('click', function() {

            var Img = $(this).attr("data-src");
            $("body").prepend(Popup);
            $(".bg").height($(window).height() * 4);
            $(".wrapper img").attr("src", Img);

            $(".prev-image").bind('click', function() {
              var prev = $(".image-container").find("img[src='" + Img + "']").parent().prev('a').find("img").attr('src');
              if (!prev || prev.length === 0)

                Img = prev;
              }
            });

            $(".next-image").bind('click', function() {
              var next = $(".image-container").find("img[src='" + Img + "']").parent().next('a').find("img").attr('src');
              if (!next || next.length === 0)
                return false;
              else {
                $(".wrapper img").attr("src", next);
                Img = next;
              }
            });

            $(".close").bind('click', function() {

                .closest(".wrapper").remove();
              $(".bg").remove();
            });
          });
        }

Answer 1

The URL returns a 403 error; this has nothing to do with your client side code at all.

The most likely causes for it are that:

• Automatically generated directory listings are disabled (which requires a server configuration change to alter, e.g. for Apache: the indexes option).
• the directory on the server has file permissions set such that the user the web server software runs as can't read it (typically changed with chmod)
