cache_dir

[Hazel Jane Aquino <hashjane@xxxxxxxxx>]

hi..:)
im new to squid. how will i know that the number i specify as an amount 
of disk space (in megabytes) for cached objects is being use by squid. 
is there an error msg stating that disk is full? or a user will just 
redirected to a page saying "The proxy server is refusing connections".
for instance, setting is cache_dir ufs /var/squid/cache 100 16 256. and 
/var/squid/cache is now 100MB in size, will i be promted that disk is 
full or while browsing i will be redirected to a page.

tnx in advace..:D
