MVC3 Custom Route has issues with Virtual Directory

I have this in my global

 //custom route
 routes.MapRoute(
      "DownloadInstall", // Route name
      "{controller}/{action}/{id}/{logonserver}", // URL with parameters
      new { controller = "Software", 
           action = "DownloadInstall" }  // Parameter defaults
 );

 //custom route
 routes.MapRoute(
      "DownloadHelp", // Route name
      "{contr开发者_运维问答oller}/{action}/{id}/{logonserver}", // URL with parameters
      new { controller = "Software", 
          action = "DownloadHelp" }  // Parameter defaults
 );

 //default route
 routes.MapRoute(
      "Default", // Route name
      "{controller}/{action}/{id}", // URL with parameters
      new { controller = "Software", action = "Index", 
           id = UrlParameter.Optional } // Parameter defaults
 );

and I invoke custom routes in javascript (which works great) like this:

 window.location.href =  '/Software/DownloadHelp/' + @Model.ID +'\/' + 
      getLogonServer(); 

However, as soon as I moved this to an IIS7 box which has a virtual directory, my default routes were smart enough to prepend with the virtual name...however my javascript based routes aren't found because the virtual directory isn't prepended.

I would try and use the Url helper if I were you, but I realize the javascript function result will be a problem.
I'm not sure if that will work, but you could try and build up your link like this:

var server = getLogonServer();
window.location.href = '@Url.Action("DownloadHelp", "Software", 
    new { Model.Id, logonserver = ""})' + '/' + getLogonServer();

What definitely would work is making getLogonServer() an Html helper function instead of a javascript function, but I don't know if that's an option for you.

I resolved it by using @Url.Content helper as such:

window.location.href =  '@Url.Content("~/Software/DownloadInstall/")' + @Model.ID +'\/' + getLogonServer();
