    Hello Sam.

     

    You have the iRule already explained here

    https://devcentral.f5.com/s/articles/http-request-cloning-via-irules-part-1

     

    The idea is to use High Speed Logging to send a clone of the initial packet to another set of servers (pool).

     

    Other idea is to use sideband connections with the HSSR feature.

    Everything depends on your scenario.

     

    BTW, I would appreciate if you mark my answer as the best or give me some upvotes.

    Thanks.

     

    KR,

    Dario.
