1. A method implemented by a network traffic management system comprising one or more network traffic apparatuses, client devices, or server devices, the method comprising:
generating metadata comprising state information for a received network packet, wherein the state information includes data associated with a session history of the received network packet;
inserting the generated metadata into an additional network packet, wherein the additional network packet is created for the received network packet;
sending the received network packet to a destination device without including the generated metadata and without performing a network diagnostic operation on the received network packet; and
performing the network diagnostic operation only on the additional network packet.
