Clearing the cache

[Ric <lists@xxxxxxxxxxx>]

In http://wiki.squid-cache.org/SquidFaq/ClearingTheCache, it says to  
purge the cache via:

squid -k shutdown
rm -r /squid/cache/*
squid -z
squid

I've seen elsewhere say to use:

squid -k shutdown
echo '' > /squid/cache/swap.state
squid

I like this second one -- it's fast and simple (and less scary than a  
recursive rm with fumbling fingers).  Any problems with it?
