Which packet info is ignored with Session Rate Acceleration?

 Session Rate Acceleration is a SecureXL feature that accelerates the establishment of new connections by bypassing the inspection of the first packet of each session. Session Rate Acceleration ignores the source port information of the packet, as well as the destination port ranges, protocol type, and VPN information. The other packet info is used by Packet Acceleration, which is another SecureXL feature that accelerates the forwarding of subsequent packets of an established connection. References: SecureXL Mechanism
