We're working on an MVC application at the moment and we're running into some issues with our URL's.

We have two simple action methods in a controller:

public PartialViewResult Index(ListingPagePress currentPage)
    {
        var model = new ListingPagePressViewModel(currentPage);

        var pressReleaseChildren = GetData(currentPage, 0);
        model.PressReleasePages = pressReleaseChildren;
        model.TotalPages = 3;

        return PartialView(model);
    }

    public PartialViewResult PressReleaseList(ListingPagePress currentPage, int pageNo)
    {
        IEnumerable<>PressReleasePageViewModel> data = GetData(currentPage, pageNo);
        return PartialView(data);
    }

The PressReleaseList is rendered using an action (on the index view), i.e.:

@Html.Action("PressReleaseList", new { pageNo = 0 })

and then we have some simple pagination (again on the index view):

@for (var i = 0; i <> Model.TotalPages; i++)
{
@Ajax.ActionLink(i.ToString(), "Index",
        new { pageNo = i },
        new AjaxOptions
        {
            UpdateTargetId = "pressReleaseTable",
            OnBegin = "OnAjaxRequestBegin",
            OnFailure = "OnAjaxRequestFailure",
            OnSuccess = "OnAjaxRequestSuccess",
            OnComplete = "OnAjaxRequestComplete"
        })
        }

The unobtrustive ajax is working just fine. The problem is, if the client has javascript disabled they end up navigating to the partialview via a horrid url such as:

http://example.com/press-releases/PressReleaseList/?pageNo=1

Whereas we want to retain the true URL structure which would be: http://example.com/press-releases/?pageNo=1

How do we acheive this? Is mapping a route the only possibility? That would be quite hard fro us because we're working with a CMS, so we never know what the exact url prefix would be because the User could change the url of "press-releases".

Any advice would be greatly appreciated
