A good alternative is also to use mod_disk_cache on a directory which a (mounted) ramdisk cache. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
