The looked-up data are downloaded from a first remote site (103, 104, 105) and/or are available on a data medium. The method comprises a step for inserting (302, 402) on the fly at least one active code into the page (200) by means of a terminal (100).

Abstract: A consultation optimization method for a data page (200), consulted on at least one terminal (100) by at least one user. The page (200) is downloaded from a remote site (103; 104; 105; 106) via a communication network. The method comprising an on-the-fly insertion step (302; 402) of at least one active code (201) enabling the execution of a corresponding algorithm in the page (200) by at least one component (101; 102) of the network architecture.
