Response.End() and CompleteRequest()

Question

What are the advantage and disadvantage for each of Response.End() and CompleteRequest()? Where should I and should I not use them? I looked at this qu

Answer 1

HttpResponse.End flushes the output buffer to the client and terminates the current request-handling thread (this is bad), whereas HttpApplication.CompleteRequest tells ASP.NET to immediately skip all future stages in the ASP.NET pipeline and jump directly to the EndRequest step (which also raises the HttpApplication.EndRequest event). The request thread then proceeds with normal end-of-life cleanup.

So, Response.End is like an ejector seat: it quickly ends things, but means you lose control and might be unnecessarily harsh. Whereas CompleteRequest is like making an emergency landing at the nearest airport.
