Claim:
1. A computer-implemented method comprising: receiving, by an ad server and from a client, a first request for a first advertisement from an advertiser associated with an advertiser group, the first advertisement being identified by a first reference to a hostname that identifies the ad server and the advertiser group; in response to the first request for the first advertisement from the advertiser, determining, based on the hostname, that the first request is associated with the advertiser group, and generating a first advertisement packet that includes the first advertisement and a client cookie associated with the advertiser group and the client, the first advertisement packet being of a first size; sending, to the client, the first advertisement packet; receiving, by the ad server and from the client, a second request for a second advertisement from a different advertiser associated with the advertiser group, the second advertisement being identified by a second reference to the hostname that identifies the ad server and the advertiser group; determining, by the ad server, that the advertiser group identified by the first reference matches the advertiser group identified by the second reference; determining, by the ad server, that the ad sever has previously sent, to the client, the client cookie associated with the advertiser group; based on determining that the advertiser group identified by the first reference matches the advertiser group identified by the second reference and determining that the ad server has sent, to the client, the client cookie associated with the advertiser group, generating a second advertisement packet that includes the second advertisement and does not include an additional client cookie, the first packet being of a second size that is smaller than the first size; and sending, to the client, the second advertisement packet.
