First, i'll explain my organization's configuration: we have a linux mandrake 9 with Squid giving internet access to all organization's workstations (windows98, windowsXP). >From a workstation running windowsXP a user can't download some type of files (doc,pdf,pps). But from a windows98 workstation that is at the same "http_access" level in squid.conf the user doesn't have any problem. Can someone help me? Thanks --------------------------- Ing. Alejandro S.
