How to end request with 404 in an IHttpModule?

I'm writing a new IHttpModule. I would like to invalidate certain requests with 404 using a BeginRequest event handler. How do I terminate the request and return a 404?

Another possibility is:

HttpContext.Current.Response.StatusCode = 404; 
HttpContext.Current.Response.Flush(); // Sends all currently buffered output to the client.
HttpContext.Current.Response.SuppressContent = true;  // Gets or sets a value indicating whether to send HTTP content to the client.
HttpContext.Current.ApplicationInstance.CompleteRequest(); // Causes ASP.NET to bypass all events and filtering in the HTTP pipeline chain of execution and directly execute the EndRequest event.

You can explicitly set the status code to 404 like:

HttpContext.Current.Response.StatusCode = 404; 
HttpContext.Current.Response.End();

Response will stop executing.

You can do the following:

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("Location", l_notFoundPageUrl);
HttpContext.Current.Response.Status = "404 Not Found";
HttpContext.Current.Response.End();

Assign l_notFoundPageUrl to your 404 page.

You can try with 

throw new HttpException(404, "File Not Found");
