on
The onReconnect function is triggered whenever a reconnect request is received by the library. It is worth noting that Proof of Work will not be involved if this is the case, assuming it is enabled in the first place. Instead of transmitting the password, the client will transmit the seed used by the previous login connection. If the seed does not match with what the server knows, the request should be rejected. If the reconnect is successful, the server should replace the Session object in that player with the one provided by the response handler. The old session will close or time out shortly afterwards, if it already hasn't.
Parameters
the handler used to write a successful or failed reconnect response, depending on the decisions made by the server.
the login block sent by the client, containing all the information the server will need.
