Abstract:
1. A method, comprising: receiving, at a first server, a request for content, from a first client; determining, at the first server, information including at least one network resource for which a request, when made by the first client, is usable to identify the first client; sending, by the first server to the first client, a web page that includes a first set of elements that includes a reference to the at least one network resource, wherein, when the first client attempts to display the web page, the first client will initiate one or more requests for at least a portion of the first set of elements, wherein the one or more requests includes a first request for the at least one network resource, and wherein initiating the one or more requests causes information associated with a subset of the first set of elements to be stored at the first client; receiving, at a second server, one or more requests from the first client for a second set of elements, wherein the one or more requests includes a second request that is associated with the at least one network resource; and in response to receiving the one or more requests for the second set of elements, identifying, by the second server, the first client, at least in part by determining which elements are stored at the first client, and serving information associated with the at least one network resource to the first client.
