Dear Erik, Thank you for your reply. I checked out /proc directory but I don't see 'drop_caches' So I looked up online and it said that this was added in 2.6.16 but my kernel is 2.6.11. Do you by any chance know how to configure with 2.6.11? I could not find any information to do this. Thank you. Ilho <>< On 1/11/07, Erik Mouw <mouw@xxxxxxxxxxxx> wrote:

Note that this will not empty your web browsers own cache! Erik -- They're all fools. Don't worry.
