That is correct.

Squid assumes that /cache1 and /cache2 are the same size. It just
alternates between the two for every object which gets stored.

However, you can use more cache_dir lines in the proper ratio if
you have partitions of different size. If you have /P1 with 1G
and /P2 with 2G, then you could use

    cache_dir /P1/cache1
    cache_dir /P2/cache2
    cache_dir /P2/cache3

and similarly for other ratios.

You might want to do this anyway since each 'cache_dir' has 100
subdirectories. If you have too few cache_dir's then each of
the subdirectories will have 1000's of files and the time to
seek through large directory entries may slow down your cache.
