Behaviour in error situations

• When an HTTP request is received with methods other than POST, GET, PUT and DELETE, it is rejected by openUTM with HTTP status code "501 Method Not Implemented".
• If no TAC can be assigned to an HTTP request, it is rejected by openUTM with HTTP status code "404 Not Found".

• When an invalid HTTP request is received, the connection to the HTTP client is terminated after a negative HTTP response has been sent.
  

  An overview of the HTTP status codes used by openUTM in error situations can be found in the chapter "HTTP Status Codes" in the openUTM manual “Messages, Debugging and Diagnostics”.
