do/protect protected-user.r -> secure[file [allow read]] do %protect-user.r for ram-cache, i wrote a ramdisk-scheme long ago. which loaded missing files from disk and cached. eventually i find it, if you ask. but since it was very simple and there are some scheme-examples now, you may have more fun to do it yourself ;) you have to change files to ram://file, but since the disk is readonly you wil trap wrong file-access. > > -MAx -Volker -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.
