analyzing data in a fastl4 VIP

Is it possible to analyze data passing through a fastl4 VIP ? I need to be able to check the presence of some strings in the payload. Since all traffic will be on layer4 not sure if it can be done, but is there a way it can be done without changing the type of the VIP to standard?

    In short, no. FastL4 means "apply hardware acceleration when possible". When hardware acceleration is used, generally only the first segment from a flow is passed to the control plane. All of the other segments are handled by the ASIC/FPGA hardware only. That hardware cannot perform segment data inspection.
