Abstract
A switch may be used to force the expiration of a cookie on a user's system by inserting an expiration field into the cookie contained in a network response packet. Additionally, a mechanism is provided to delete or damage a cookie contained in a network request packet, so that server software is not disrupted by the receipt of a cookie. Deleting a cookie results in a cleaner request, but damaging a cookie may be more efficient in certain circumstances. By providing these features, an efficient cookie switching design is provided.

A computer implemented method comprising:
- at a network device configured to perform packet switching,
- swapping a first odd byte/even byte pair of a cookie header name with a second odd byte/even byte pair of the cookie header name if the cookie header name begins at an even byte from a beginning point of a header of a network request packet;
- and
- swapping a first even byte/odd byte pair of the cookie header name with a second even byte/odd byte pair of the cookie header name if the cookie header name begins at an odd byte from a beginning point of the header of the network request packet.
