IIS的MVC3 JSON呼叫问题

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: 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!

Has your IIS been configured with a virtual directory? What happens if you put /{controllerName}/GetAllUsers into your browser? Do you get a response or a 404?

The URL you are passing to the $.post is wrong.

It should be either,

$.post("/Register/GetAllUsers", ...) // assuming the controller is RegisterController

or

$.post('@Url.Action("GetAllUsers", "Register")',..
