MVC3 JSON call issue with IIS
===

I'm working on MVC3 UserManagement and on local (VS2010) all seems to be working fine but on IIS(7.5) it just won't show any response to JSON post.

Table for users generator:

    this.init = function (tableSelector) {

    // get user table
    userTable = $(tableSelector);

    // fill the user table with all 
    $.post('/{controllerName}/GetAllUsers', {}, function (users) {

      // add users to table
      for (var i in users) {
        appendUser(users[i]);
      }

      //initialize table sorter and pager
      userTable.tablesorter({ widthFixed: true, widgets: ['zebra'] }).tablesorterPager({ container: $("#pager"), positionFixed: false, removeRows: false });

      // bind user action link event handlers for all rows
      userTable.on('click', '.delete-user', deleteUser);
      userTable.on("click", ".unlock-user", unlockUser);
      userTable.on("click", ".manage-roles", manageRoles);
    });
  }

Routes register method:

    public static void RegisterMe()
    {

      var routes = RouteTable.Routes;

      using (routes.GetWriteLock())
      {
        routes.MapRoute("SimpleUserManagementRoute",
          "SimpleUserManagement/{action}",
          new { controller = "UserManagement", action = "GetAllUsers" },
          new string[] { "SimpleMvcUserManagement" });
      }

    }

Controller part:

    public IUserAccountService _accountService { get; set; }

    public JsonResult GetAllUsers()
    {
      var users = _accountService.GetAllUsers();
      var result = from MembershipUser user in users
                   select CreateJsonUserObject(user);

      return Json(result);
    }

Now  by looking around StackOverflow, I've found that issue lies with strong-coded URL.
Reference: http://stackoverflow.com/questions/5044059/mvc-3-json-call-not-working-in-iis

And i've tried replacing my URLs with those mentioned in the reference, but of course it didn't work since I don't know where/how to `stringify` my url :( , also not sure if that solution would even work with this.

Please help. TY!
