Application_Error

I recently discovered that the IIS worker process in production was crashing 2-3 times per week. I noticed in the exception logs that the its because of an UnhandledException. I investigated and found that the Global.asax had no Server.Transfer call.

I then did some googling and it appears that it's better to use Response.Redirect. Is this true, I keep on getting mixed comments on this...

    void Application_Error(object sender, EventArgs e)
    {
        // Code that runs when an unhandled error occurs
        if (null != Context && null != Context.AllErrors)
            System.Diagnostics.Debug.WriteLine(Context.AllErrors.Length);

        //bool isUnexpectedException = true;
        HttpContext context = ((HttpApplication)sender).Context;

        Exception ex = context.Server.GetLastError();
        if (ex.InnerException != null)
            ex = ex.InnerException;

        LogManager.ExceptionHandler(ex);

        Server.Transfer("GeneralError.aspx");
    }

It depends on if you would want your user to see the "redirection". Personally I would use Response.Redirect for this case.
