How can I get the IIS substatus code from an Exception?

Question

I\'m handling exceptions with an HttpModule in a manner such as this:

int errorCode = 500;
HttpApplication httpApp = (HttpApplication)sender;

t

You don't want the inner exception. You want:

HttpException httpEx = httpApp.Server.GetLastError() as HttpException;
if (httpEx != null)
    errorcode = httpEx == null ? 0 : httpex.GetHttpCode();
