1. A method including:
- detecting by a connection proxy that a network communication link between a client terminal and an intermediary device has been lost, wherein the client terminal communicates with an electronic exchange using a communication session established for the client terminal at the intermediary device;
providing by the connection proxy one or more communication session maintenance messages to the intermediary device to maintain the communication session at the intermediary device for a predetermined period of time in response to detecting that the network communication link has been lost;
providing by the connection proxy initial download data and market data received after detecting that the network communication link has been lost to the client terminal if the network communication link between the client terminal and the intermediary device is restored during the predetermined period of time; and

Abstract
System and methods for a connection proxy server are described. According to an example method described herein, a connection proxy server stores subscription, product tables as well as other downloads that are provided to a client terminal during initialization stage as well as later during a trading session. Upon detecting that a connection between the client terminal and a gateway is lost, the connection proxy maintains a communication session created for the client terminal at the gateway and receives data intended for the client terminal. If the connection is re-established between the client terminal and the gateway during a predetermined period of time, the connection proxy provides the stored data to the client terminal thus avoiding a surge in processing resources at the gateway due to the necessary downloads.
