REGRESSOR.NET

Regressor.NET is a service that collects information about website crashes, and periodically resends the exact HTTP Request that caused any one of those crashes... Regressor.NET can be integrated into existing applications in two basic ways, either via a custom Base Page or through direct API calls from the Web Application. Regressor.NET provides a custom Page object, derived from System.Web.Page, that can be used as the base for any application pages, and will automatically detect and log unhandled exceptions. Alternately, Regressor.NET exposes a number of public methods that can be called to log exceptions manually.
