Ideally there should be difference between internal server errors, and errors due to the server working as a gateway to another and getting an invalid response. This helps know if the problem is as a result of the server itself, or some external service it has to interface with

500 Internal Server Error -

The server has encountered a situation it doesn't know how to handle.

502 Bad Gateway -

This error response means that the server, while working as a gateway to get a response needed to handle the request, got an invalid response.
In other words a server on the internet received an invalid response from another server.

504 Gateway Timeout -

This error response is given when the server is acting as a gateway and cannot get a response in time.

The handleError method of Controller doesn't end requests when headers have been sent.
This is mainly because it uses the headerSent flag to determine whether it should send a response in the case of an error
