Mechanisms and techniques provide a system for performing messaging between a message server and a message client. Embodiments operate to receive a first message to be sent to a messaging client and establish a first connection to the messaging client. The system then transmits a message processing script and the first message over the first connection to the messaging client. The message processing script enables the messaging client to display the first message and to receive and display at least one second message over the first connection to the messaging client. The system maintains the first connection in an open state after transmitting the first message to the messaging client. The system then receives a second message to be sent to the messaging client and transmits the second message over the first connection to the messaging client for receipt by the message processing script, while continuing to maintain the first connection in an open state. This can be repeated for subsequent messages using the same connection.
