Method and computer system for adjusting caches of network computers. A first computer (901) has a first cache (921-1) and a first journal (111). A second computer (902) has a second cache (922-1) and a second journal (112). A journal entry (112-10) of the second journal (112) indicates a modification of an object (191) on a third computer (903). The first computer (901) sends a representation (121-2) of a previous latest journal entry (112-11) of the second journal (112) to the second computer (902). The second computer (902) compares the representation (121-2) with a corresponding portion (112-1) of the second journal (112). The second computer (902) transmits (440) from the second journal (112) to the first journal (111) each journal entry (112-10) in the second journal (112) that is newer that the previous latest journal entry (112-11). The first computer (901) adjusts (450) the first cache (921-1) by deleting objects (191*) that are outdated according to the first journal (111). The first computer (901) further updates (460) the representation (121-2) stored on the first computer (901) according to the first journal (111). <IMAGE>
