Url helper for full url in asp.net mvc-3

The @Url.RouteURL() does not quiet answer this question. It does work for named routes but falls short for arbitrary virtual paths. Here is quick helper method that generates full outbound url. You can create overloads for various schemes (http[s]) depending on the degree of control desired.

public static class UrlHelperExtension
{
    public static string ContentFullPath(this UrlHelper url,string virtualPath)
    {
        var result = string.Empty;
        Uri requestUrl = url.RequestContext.HttpContext.Request.Url;

        result = string.Format("{0}://{1}{2}",
                               requestUrl.Scheme,
                               requestUrl.Authority, 
                               VirtualPathUtility.ToAbsolute(virtualPath));
        return result;
    }
}

See this blog post for the answer.

Basically, all you need to do it include the protocol parameter e.g.

Url.Action("About", "Home", null, "http")
