Method and system for dynamic interleaving

A method performed by a server having one or more processors and a network interface, the method comprising:

• acquiring a first request message sent over a persistent connection established between the server and a client station, wherein the first request message comprises one or more packets including a header having a first unique identifier and first control information indicating a first priority for the first request message that is different than a second priority for a second request message;
• preparing a first response message for providing first content associated with the first request message over the persistent connection and a second response message for providing second content associated with the second request message, wherein the first response message comprises one or more packets including the first unique identifier that associates the first response message with the first request message and the second response message comprising one or more packets including a second unique identifier that associates the second response message with the second request message;
• and
• transmitting, via the network interface, the first response message and the second response message over the persistent connection in an interleaved fashion, where the first control information allows the server to control an ordering of the first and second response messages.
