was cached but had one problem: the dimension of object in cache and
dimension in HTTP download is different. In this case the client
receive only 338163 byte from squid cache and download the end of file
from internet. In squid cache I have 330-350 KB sizes .exe objects from
windowsupdate and files can be really 5 MB sizes. If I can store this
files completely, I resolve a great problem in my net (16 clients with
ISDN 64Kb connection).
