squid and chroot

[Tom Penndorf <tpenndorf@xxxxxxxxxxxxxxxxx>]

Hello,

i trying to configure squid with chroot. When i start squid, i get the 
following error message:
FATAL: MIME Config Table on//etc/squid3/mime.conf: (2) No such file or 
directory
Squid Cache (Version 3.0.STABLE15): Terminated abnormally.
CPU Usage: 0.008 seconds = 0.008 user + 0.000 sys
Maximum Resident Size: 0 KB
Page faults with physical i/o: 0

The file exists. Does someone know, which dir is used for chroot? The 
parameter cache_dir is unknown....

Thanks,
Tom
