MVC 2：当调用者定义了 MapRoute 时，Ajax.ActionLink 重定向到新页面

Question

一切正常，直到我还没有为具有 AJAX 的页面定义路由映射。

控制器

  public ActionResult SessionDetails(int id, int collectionId, int sessionId) {
    var model = new LegalActsListViewModel();
    model.Setup(id, collectionId, sessionId, ApplicationContext.SessionService);
    return PartialView("LegalActsListControl", model);
    }

视图

<%: Ajax.ActionLink(session.Name, "SessionDetails", "Institution", new { id = Model.InstitutionId, collectionId = Model.CollectionId, sessionId = session.Id }, new AjaxOptions { UpdateTargetId = "session_" + session.Id, OnSuccess = "updatePlaceholder", HttpMethod = "Post", InsertionMode = InsertionMode.Replace })%>

上面的内容与默认路线图完美配合。目前我已添加路线图如下：

routes.MapRoute("Institution_Collection_Terms", 
    "institution/{id}/collection/{collectionId}/terms", 
    new { controller = "Institution", action = "Terms" }, 
    new { id = @"\d+", collectionId = @"\d+" });

PartialResult 被重定向到：

 http://localhost:9085/Institution/SessionDetails/850?collectionId=22184&sessionId=77

这是所有路线：

routes.MapRoute("Institution_Collection_Keywords",
            "institution/{id}/collection/{collectionId}/keywords",
            new { controller = "Institution", action = "Keywords" },
            new { id = @"\d+", collectionId = @"\d+" });
        //routes.MapRoute("Institution_Collection_Terms",
        //    "institution/{id}/collection/{collectionId}/terms",
        //    new { controller = "Institution", action = "Terms" },
        //    new { id = @"\d+", collectionId = @"\d+" });
        routes.MapRoute("Institution_Collection_Yearbooks",
            "institution/{id}/collection/{collectionId}/yearbooks",
            new { controller = "Institution", action = "Yearbooks" },
            new { id = @"\d+", collectionId = @"\d+" });
        routes.MapRoute("Institution_Collection_YearbookDetails",
            "institution/{Id}/collection/{collectionId}/yearbook/{year}/{month}",
            new { controller = "Institution", action = "YearbookList", month = UrlParameter.Optional },
            new { Id = @"\d+", collectionId = @"\d+", year = @"^(19|20)\d{2}$" });
        routes.MapRoute("Institution_Collection_List",
            "institution/{id}/collection/{collectionId}/list",

            new { id = @"\d+", keywordId = @"\d+", collectionId = @"\d+" });
        //routes.MapRoute("Institution_Collection_TermsDetails", 
        //    "institution/{id}/collection/{collectionId}/session/{sessionId}/details",
