Amos, thanks for this information. From Leonardo recommended 'sqstat'
PHP script from Alex Samorukov about doing what I need. I'm not
a programmer, and I would have had a problem write such a program.
And from my very quick view, I not found useful informations about
cachemgr interface, searching for 'cachemgr' at
http://www.squid-cache.org/ return nothing and searching at
http://wiki.squid-cache.org/ return reference to
http://wiki.squid-cache.org/ProgrammingGuide/CacheMgrApi
, but it seems as there are only some basest informations.
(which does not matter, I did not know how to program it anyway)

Thanks, Franta Hanzlik
