Yes, I k now, this was my second option...but I have some doubt on this
solution:

1) can I specify different expiral time for each cache dir? I mean: big
multimedia files do not need to be replaced that often in cache right?

2) supposing to have two different cache dir, the first one for normal
web doc and the second one for big multimedia files, whenever squid
needs space to cache, let's say, another web doc (small file) does it
start applying the replacement policy only on the small file cache_dir
or even in the big file cache dir? I don't want it to purge big
multimedia files, when it needs to cache only a small web doc!!!

Well, if I need to cache very big files, let's say about 1GB in size, I
can't set m_o_s to 128kb or I would never cache files bigger than
128kb...Am I wrong?
