I-rule APM: logs: how to send rx:tx per tcp session on a webportal

IP::stats is a very helpful command for measuring bytes in and out. For example:

when CLIENT_CLOSED
{
    log local0. "Bytes In:[IP::stats bytes in]"
    log local0. "Bytes Out:[IP::stats bytes out]"
}

This iRule will log out the bytes in and out for every TCP connection.

Here is the link to the documentation for IP::stats in case you want to do more research on your own.
