Alternative to Response.End()

asp.net

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.

Simon, did you actually mean 'System.Web.Mvc.Html.FormExtensions', not 'Microsoft.Web.Mvc.FormExtensions'? There is 'Microsoft.Web.Mvc.FormExtensions' class (http://aspnet.codeplex.com/SourceControl/changeset/view/22929#266407) but there is no Form method. Maybe you are using old version of Microsoft.Web.Mvc.dll ? Open your Microsoft.Web.Mvc.dll in Reflector - on my machine Microsoft.Web.Mvc.dll have version 1.0.0.0 and there are 4 methods:

public static MvcForm BeginForm<TController>(this HtmlHelper helper, Expression<Action<TController>> action) where TController: Controller;
public static MvcForm BeginForm<TController>(this HtmlHelper helper, Expression<Action<TController>> action, FormMethod method) where TController: Controller;
public static MvcForm BeginForm<TController>(this HtmlHelper helper, Expression<Action<TController>> action, FormMethod method, IDictionary<string, object> htmlAttributes) where TController: Controller;
public static MvcForm BeginForm<TController>(this HtmlHelper helper, Expression<Action<TController>> action, FormMethod method, object htmlAttributes) where TController: Controller;

Declaring Type: Microsoft.Web.Mvc.FormExtensions

Assembly: Microsoft.Web.Mvc, Version=1.0.0.0

UPDATED:

I've dowloaded ASP.Net MVC Membership Starter Kit Preview 5 (0.5). Microsoft.Web.Mvc.dll from bin folder have 1.0.0.0 vesion, but it is older than Microsoft.Web.Mvc.dll for ASP.NET MVC v1.0. You can download last version of Microsoft.Web.Mvc.dll there.

C# – Exception Handling Application Block Exception Handler running in ASP.NET cannot call Response.End()

Have a look at ELMAH.
There are lots of articles and how-to's on ELMAH, just google or bing for it :-)

Advantages
+ It logs almost everything
+ Email notification
+ Remote viewing of errors

I would suggest to use that and redirect to a default error page, as Ariel mentioned.
