The invention relates to a system and method for caching a network connection. The system sustains connections between a server and one or more back-end databases. The server may establish multiple connections with one or more back-end databases based on data requests from one or more users. The server may determine one or more back-end databases from which the data requests may be satisfied. After receiving the data, the users, using an end-user device, may request disconnection of a connection between the end-user device and the server. The server, however, sustains the connection with the back-end database from which the data was retrieved. The server may use this connection to satisfy other data requests without re-establishing a connection with that back-end database.
