asp mvc 404 when + in url - asp.net-mvc-routing

Question

I have problem with asp mvc 3 application. When I put the + character in a url I always get a 404 error. All requests are ajax get request.
If I make this request Test/Details/+ I get 404: Test/Details/+
This is request in fiddler: GET /Test%2FDetails%2F%2B?t=1318678807718 HTTP/1.1
Here are routes.
routes.MapRoute(
"PagingTwoTest", // Route name
"{controller}/{action}/{tag}/p{currentPage}/p{secCurrentPage}/{*term}", // URL with parameters
new { secCurrentPage = UrlParameter.Optional, term = UrlParameter.Optional }, // Parameter defaults
new { currentPage = "\\d+", secCurrentPage = "\\d+" }
);
routes.MapRoute(
"PagingTwo", // Route name
"{controller}/{action}/p{currentPage}/p{secCurrentPage}/{*term}", // URL with parameters
new { secCurrentPage = UrlParameter.Optional, term = UrlParameter.Optional }, // Parameter defaults
new { currentPage = "\\d+", secCurrentPage = "\\d+" }
);
routes.MapRoute(
"Paging", // Route name
"{controller}/{action}/p{currentPage}/{*term}", // URL with parameters
new { term = UrlParameter.Optional }, // Parameter defaults
new { currentPage = "\\d+" }
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"DefaultName", // Route name
"{controller}/{action}/{*id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);

In your constraints you are not considering when someone enters a string you allways request a digit, so I think you can try with:
routes.MapRoute(
"TestDetails", // Route name
"{controller}/{action}/{id}", // URL with parameters
new {
controller = "Test",
action = "Details",
id = UrlParameter.Optional
}
);
So in your TestController you can request a string:
public class TestController : Controller
{
....
....
public ActionResult Details(string? id) //So you can verify if is null
{
ViewData["variable"] = id;
return View();
}
....
....
}
And in your Details.aspx you can put something like this:
<%# Page Language="C#"
MasterPageFile="~/Views/Shared/Site.Master"
Inherits="System.Web.Mvc.ViewPage" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Title, what you want
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<p> Blah, blah, blah, you request this: <%: ViewData["variable"] %> </p>
</asp:Content>
