How to prevent downloading when user's allocated size or period exceeds

It is handled using httphandler in ASP.NET. The handler code is bellow ..

public class DownloadHandler : IHttpHandler

{

       public DownloadHandler()

       {

              //

              // TODO: Add constructor logic here

              //

       }

    public bool IsReusable

    {

        get { return true; }

    }

    /// Enables processing of HTTP Web requests by a custom HttpHandler that implements the <see cref="T:System.Web.IHttpHandler"/> interface.

    /// </summary>

    /// <param name="context">An <see cref="T:System.Web.HttpContext"/> object that provides references to the intrinsic server objects (for example, Request, Response, Session, and Server) used to service HTTP requests.</param>
