Maintaining active connection
By default, the CliSiTef feature when making a transaction with the SiTef server is: making the connection, exchanging messages and disconnect at the end of the transaction.
If there is a need to keep the connection with SiTef always active, the parameter MantemConexaoAtiva must be included in the SiTef section with value 1 (one).
