if the traffic is http traffic, it will be much easier if you put http profile in the virtual server so http related traffic policy or irules will work.

there is no tcp payload insert command in irules.

f5 bigip is basically proxy.
it only forward healthy client request to the pool member.
so even basic ltm virtual server will protect servers from bad requests such as tcp syn flood, http slow loris, etc.
