Abstract

A method and apparatus for dynamically encoding transactional information into a document over a network. The transactional information may include information about client data, object properties, or network conditions. The document may contain embedded links with embedded objects that can be requested by a client. The embedded links may contain URLs with associated domain names. The transactional information may be inserted into the domain name so that when the object request is subsequently translated by a DNS server, the DNS server can utilize the transactional information to intelligently translate the domain name into an IP address of a network device that can most advantageously serve the request.
