This static method returns you full http path to root folder of your application (web site or virtual directory)

public static string GetAppRootUrl(bool endSlash)
{
    string host = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority);

    string appRootUrl = HttpContext.Current.Request.ApplicationPath;
    if (!appRootUrl.EndsWith("/")) //a virtual
    {
        appRootUrl += "/";
    }
    if (!endSlash)
    {
        appRootUrl = appRootUrl.Substring(0, appRootUrl.Length - 1);
    }
    return host + appRootUrl;
}

So, you can write in master page:
