Abstract
An identifier of an action that can be produced through a network, such as a page identifier or other substrate identifier with a counterpart digital page accessible through a network, is used to obtain a network address. The identifier is provided to a first machine such as a router, and the first machine uses the identifier to obtain a first network address that is for a set of identifier values that includes the identifier's value. The first network address is then used to provide the identifier to a second machine such as a server. The second machine uses the identifier to obtain a second network address that is for the value of the identifier. The second network address, when provided on the network, produces the action identified by the value of the identifier. The identifier can be read from a coded substrate by image input circuitry and the image signals can be used by a third machine, such as a processor in a pointer, to provide the identifier to the first machine. The pointer's processor can also cache network addresses obtained from the first machine for use with subsequent identifiers in the same set.
