Claim:
1. A method of recording application layer flow information via a multi-connection intermediary device, the method comprising: receiving, by a device intermediary to a client and a server, a plurality of flows between the client and the server across a first transport layer connection established between the device and the client and a second transport layer connection established between the device and the server; recording, by a metering process of the device, a first record set of one or more application layer characteristics of a first application layer flow of the plurality of flows traversing the first transport layer connection, the first record set comprising a first connection identifier for the first transport layer connection and a first flow identifier for the first application layer flow; recording, by the metering process, a second record set of one or more application layer characteristics of a second application layer flow of the plurality of flows traversing the second transport layer connection, the second record set comprising a second connection identifier for the second transport layer connection and a second flow identifier for the second application layer flow, wherein the second connection identifier has a same value as the first connection identifier; determining, by the metering process, that an application layer transaction of the first flow identified by the first flow identifier corresponds to the application layer transaction of the second flow identified by the second flow identifier; and recording, by the metering process responsive to the determination, a transaction id for the application layer transaction in each of the first record set and the second record set of one or more application layer characteristics.
