Problem with Url.Content in ASP.NET MVC on Default Route - asp.net-mvc

Question

If I use the following line in my default view /Home/Index
<script language="javascript" src="<%=Url.Content("~/Scripts/jquery-1.3.2.js")%>" type="text/javascript" ></script>
If I surf to this location using the following url http://127.0.0.1:9999/Home/Index
the page gets rendered correctly
<script language="javascript" src="/Scripts/jquery-1.3.2.js" type="text/javascript" ></script>
If I use the following url http://127.0.0.1:9999/ (default wired to Home/Index) the page renders this:
<script language="javascript" src="//Scripts/jquery-1.3.2.js" type="text/javascript" ></script>
Does anyone has any idea how to solve this issue?
EDIT:
FYI: I'm using ASP.NET mvc 2 RC
And this is my route configuration:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);

If you use IIS6 or WinXP Cassini you should register one more route:
if (Environment.OSVersion.Version.Major < 6) // IIS6 and WinXP Cassini
{
routes.MapRoute(
"Root",
"",
new
{
controller = "Home",
action = "Index",
id = UrlParameter.Optional
}
);
}

I had a very similar problem with Asp.net using Request.ApplicationPath... and wrapped it as follows
public string AppRoot()
{
var appPath = Request.ApplicationPath;
if (appPath.EndsWith("/"))
return appPath;
else
return appPath + "/";
}

Well, alternatively you can do the following:
create a key in appSettings section of web.config file.
<add key="DomainName" value="http://http://127.0.0.1:9999/" />
Now, whenever you want to assign "src" value of any image, javascript of css file, you can use this key. it will be define a root for you and after that you can define at what path you have placed your file. i.e. in your case:
<script language="javascript" src="<%=System.Configuration.ConfigurationManager.AppSettings["DomainName"] %>Scripts/jquery-1.3.2.js" type="text/javascript" ></script>

Why are you keeping your id as an empty string? I think this may be causing the problem. You may find better results by trying the following:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
to this
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", UrlParameter.Optional } // Parameter defaults
);
