I handle a request begin_request. At the moment i use Response.End() to stop asp.net from doing whatever else. Response.End() throws an exception is there a non exception way i can end the request?

If your wondering why i have no file its bc i tell nginx what file to serve via http response header thus i have nothing else to do in asp.net. Response.End throws an exception which has to collect stack info and all of that. I obviously dont need that and from my past questions i know throwing exceptions are expensive. So how what can i do where?

HttpResponse.End() throws an exception by design; it has to to work.

Only when the ThreadAbortException is thrown, does the thread that's rendering the response end. If there's no exception, the response doesn't end.

One alternative would be to call HttpContext.Current.ApplicationInstance.CompleteRequest instead. This will prevent further code from executing by jumping straight to the Application_EndRequest event.

  • Yes so how do i not get the exception? I saw your answer before the edit and i dont see an overload in msdn nor autocomplete http://msdn.microsoft.com/en-us/library/system.web.httpresponse.end%28v=VS.90%29.aspx –  Oct 23 '11 at 16:00
  • @acidzombie24: You're right, that's why I edited. The method that has the overload is `Response.Redirect()`, which takes a second boolean parameter that says whether it calls `Response.End()` internally or not. – Cᴏʀʏ Oct 23 '11 at 16:06

call the HttpContext.Current.ApplicationInstance.CompleteRequest() method instead of Response.End to bypass the code execution to the Application_EndRequest event
