Claim 12:
13. A network system comprising:
a propagation server for facilitating propagation of recorded information between first-party data structures associated with different domains, the propagation server arranged for data communication via a network with web browsers of client devices, wherein the propagation server is associated with a propagation domain being a web domain, wherein the propagation server is configured to:
receive a first request from a first web browser, said first web browser associated with a first client device, wherein the first request identifies a first domain being a web domain different to the propagation domain;
determine, via data communication with the first web browser, whether a propagation data structure, being a first party data structure associated with the propagation domain, is present on the first web browser;
in a case where the propagation data structure is present:
determine an identifier from information stored with the propagation data structure;
generate first propagation information in dependence on the identifier, said first propagation information enabling determination of the identifier by the propagation server in a subsequent data communication instance between the first web browser and the propagation server, wherein said subsequent data communication instance is identified as being associated with the first domain; and
communicate the first propagation information to the first web browser; and

one or more domain servers, each arranged for data communication via a network with the web browsers of the client devices and each associated with a unique domain, wherein the propagation domain is different to the unique domains of the one or more domain servers, and wherein each domain server is configured to:
receive a communication from a web browser;
determine whether a first domain data structure is associated the communication, the first domain data structure associated with the domain of the domain server;
in response to determining that there is not a first data structure present, obtain from the web browser propagation information, the propagation information having been obtained by the web browser due to the first request communicated to the propagation server;
generate first domain data structure information based on the received propagation information; and
instruct the web browser to record in a new first domain data structure the first domain data structure information.
