First Claim
1. A method for transmission of data, called objects, through at least one communication network, between a server and at least one client terminal, at least one cache memory, designed to store at least some of the said objects transmitted by the said server, being associated with at least one of the said client terminals within the said network, the method comprising:
- managing at least one list of each object present in the said cache memory associated with one of the said client terminals by the said server or by an intermediate element of the said network, upstream of the said client terminals, in order to limit information exchanges related to the contents of the said cache memory between the said client terminal and the said server.

Abstract
The invention concerns a method for transmitting data, called objects, via at least a communication network, between a server and at least a client terminal, at least a cache memory, designed to store at least some of said objects transmitted by the server, being associated, in said network, with at least one of said client terminals. The invention is characterized in that it consists in managing, upstream of said client terminals, at least a list of objects present in said cache memory associated with at least one of said client terminals, so as to limit exchange of data concerning the content of said cache memory between said client terminal and said server.
