Object Oriented Programming is Dead

Robert Harper, a professor at Carnegie Mellon University, says:
"because it is both anti-modular and anti-parallel by its very nature, and hence unsuitable for a modern CS curriculum."

How to prevent cross site image reference by HTTP Handler in ASP.NET

http://www.blackbeltcoder.com/Articles/asp/writing-a-custom-http-handler-in-asp-net

This is a very simple handler that starts by seeing if the request came from the current domain. If not, HTML markup for an "Access Denied" message is constructed and returned.
Custom HTTP Handler

using System;
using System.Globalization;
using System.Web;

public class JpgHttpHandler : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
        HttpRequest request = context.Request;
        HttpResponse response = context.Response;

        // Try and prevent request from a different domain
        if (request.Url != null && request.UrlReferrer != null)
        {
            if (String.Compare(request.Url.Host, request.UrlReferrer.Host,
                true, CultureInfo.InvariantCulture) != 0)
            {
                response.Write("<html>\r\n");
                response.Write("<head><title>JPG HTTP Handler</title></head>\r\n");
                response.Write("<body>\r\n");
                response.Write("<h1>Access Denied</h1>\r\n");
                response.Write("</body>\r\n");
                response.Write("</html>");
                return;
            }
        }

        // Otherwise transfer requested file
        try
        {
            response.ContentType = "application/jpg";
            response.WriteFile(request.PhysicalPath);
        }
        catch
        {
            response.Write("<html>\r\n");
            response.Write("<head><title>JPG HTTP Handler</title></head>\r\n");
            response.Write("<body>\r\n");
            response.Write("<h1>Access Granted but file was not found</h1>\r\n");
            response.Write("</body>\r\n");
            response.Write("</html>");
        }
    }

    public bool IsReusable
    {
        get { return true; }
    }
}
