Here is the feedback on HTTP::close I received from F5 Support in C462406:

HTTP::close semantics are "close the connection after this request/response has been processed". Since HTTP::respond effectively completes the request/response, HTTP::close cannot be used after HTTP::respond. TCP::close can be used to gracefully close the connection after HTTP::respond, if using Connection::close is not acceptable - use of clientside is required to close the clientside if in server-side event, i.e. HTTP_RESPONSE.

So it would probably be best to use TCP::close in HTTP_REQUEST and clientside {TCP::close} in HTTP_RESPONSE (or other events in the serverside context): 

 
 when HTTP_REQUEST { 
    HTTP::respond 204 
    TCP::close 
 } 
 

 
 when HTTP_RESPONSE { 
    HTTP::respond 200 content "test" 
    clientside {TCP::close} 
 }
