Multiple servers sharing storage

Hi everybody,

I'm planning to setup several proxy servers for our
company, but I'm not sure if Apache 2.0 could solve my
issues...

1) I'm working on a mod_perl tool that filters
requests and checks them against a RDBM of blacklisted
hosts/pages. Anybody has an easier solution? (beyond
writing my own filter and chaining to another proxy
like privoxy or squid).
2) I would like to have a HA solution with two or more
active proxy-cache servers and one hot spare. I'm not
sure which are the concerns about shared NFS disks in
2.0. Which is your recomendation? Maybe we can get
some space at SAN storage, but NFS could be easier to
implement for us...

Thanks everybody!

Ivan
