Aristos,

You were right. Last afternoon just before I went home I tried creating a custom HTTP handler. And it worked nice. :-) Thanks for answering +1

public class CustomFlashHandler : IHttpHandler
{

public void ProcessRequest(HttpContext context)
{
  if (!context.User.Identity.IsAuthenticated)
  {
    context.Response.Redirect("Default.aspx?ReturnUrl=%2felVideo.aspx");
    context.Response.StatusCode = 401;
    return;
  }

  var url = context.Request.CurrentExecutionFilePath;

  if (string.IsNullOrEmpty(url)) return;

  HttpContext.Current.Response.ClearContent();
  HttpContext.Current.Response.ClearHeaders();
  HttpContext.Current.Response.AddHeader("Content-Disposition", string.Format("filename={0}", url));
  HttpContext.Current.Response.AddHeader("Content-Type", "application/x-shockwave-flash");
  HttpContext.Current.Response.WriteFile(url);
  HttpContext.Current.Response.End();
}

public bool IsReusable
{
  get { return false; }
}

}

Like Aristos said, you have to map ASP.NET to handle .swf files in IIS.

Then add the custom mapping in the application's web.config
