Phil Winstanley's Error Reporting and the Trace in ASP.Net 2.0

We've been using Phil Winstanley's ASP.Net WebException handler for a while now it's great (see http://weblogs.asp.net/plip/archive/2004/04/17/114984.aspx) the problem with it was that we couldn't get access to the Trace in ASP.Net 1.1. Doug and I spoke with Phil about it but at the time there wasn't a solution however he did say he thought there may be with the emergance of ASP.Net 2.0 (this was a few months before it was due to be released).
Now we're working in 2.0 on a regular basis I thought I'd give it a go and think I have a solution (though quite how reliable it is I'm not 100% sure). The fix is to tap into the current HttpContext and "switch" the trace's output on and then off before and after handling the exception and voila!
Here's my solution:
TraceContext t = HttpContext.Current.Trace;
t.IsEnabled = true;
WebException WE = new WebException();
WE.CurrentException = Server.GetLastError();
WE.Handle();
t.IsEnabled = false;
