Instance Method Details

#run ⇒ Object

The exception that we are generating a response for can change in the case that the configured error proc raises an exception. If this occurs, a response will be generated for that exception, instead of the original one. This is designed to avoid “hidden” errors happening, this way the server will respond and log based on the last exception that occurred.
