A method and system for forwarding messages received at a traffic manager. A traffic manager receives a message from a first connection to a client computer. At least a part of the message is to be forwarded to a server. If a connection exists to the server that matches the first connection, at least a part of the message is forwarded to the server by employing the existing connection. Otherwise, a source address is selected with which to communicate with the server. A new connection that includes the source address and a destination address associated with the server is opened. In addition, information associating the source address and the destination address with the first connection is stored. This information may then be used to map a response received from the server to the first connection.
