Control data sent in SSL

This is my exact irule:

when SERVER_CONNECTED {
    set inside 0
    TCP::collect
}

when SERVER_DATA {
    if { $inside == 0} {
        set field_offset 0
        set cipherList_len 2
        if { [TCP::payload] start_with "00" } {
            set inside 1
        } else {
            TCP::release
            TCP::collect
        }
    }
    if { $inside == 1 } {
        if { [TCP::payload] ends_with "ff" } {
            set inside 0
            TCP::release
            TCP::collect
        }
    }
}

When I receive an answer from server that starts with "00" I save all the data in F5 until I receive a "ff", the indication of the final of the answer. The connection between F5 and server is unencrypted, and between client and F5 SSL is used.

When I receive "ff" I send all data to the client. I need that all data goes in the same SSL packet, this is the reason because I do this irule, to try that F5 send the data at the same time to the client. But F5 send the information in various ssl packets, in my last test with a payload of 1464.

Anybody knows if its possible to force F5 to send all data in a SSL packet?

Thanks.
