cache mechanism

When I turn jigsaw as a proxy cache, it works well . But I don't know
how the cache works. In the cache directory I only find some files named
cached.0 ,cached.1 ... If I request a url , how can the cache know the
url is already cached or not and what is the exactly cache file name? I
guess there should exist a mapping table. But what's the table name and
where can I find it?

Furthermore if some urls are already cached , when I open a new browser
or restart the jigsaw , can it be serviced correctly? I find after
restarting the jigsaw , some cache files are renewed. for example , the
new url will be saved as cached.0 cached.1... to recover the old cache
files. So I think cache file will lost after restart jigsaw. Is it
right?

I want to know the history urls through the cache server. Where can I
find it?
