While montiroing connections, MT shows timeout value for each connection.
It would be great if another field is introduced: total duration of connection. That should also became one of the fileds that may be used for connection marking.
This would be useful for handling downloads. Now, there is no way to distinguish from web surfing and web downloading and the only way to handle it is using bursting. If connection duration info is available we would be able to recognize long http connections and deal with them, for instance by mangling them separately than other http traffic.
