And also this:
"NDB is an in-memory storage engine"
No longer true: As of MySQL 5.1.6 it's possible to store
tables on disk rather than in memory.
See http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-disk-data.html

The issue that i've come up with, is that some malformed cookies will
cause a segault when parsed. I'm hoping that the next libapreq will fix
that.
I remeber joes doing something about this. I'll have to go read it.

Taking this another step further, I don't get the impression that perlbal or
pound will achieve the "temporary" caching on the middle-proxy server
allowing the back-end server to get back to other requests.
Anyone know for sure?

It is on disk? This quote from the manual led me to think it wasn't:

There's also clustering in MySQL 5 that looks very enticing to me as an
additional layer or scale out and redundancy. It's not your typical
master/slave scenario and actaully allows for real load balancing and

As a caveat to the E-mails about caching pages using a proxy, the usefulness
of such depends on how much traffic your site will see to static pages. In
our situation, the only static pages are our "contact us" page, "privacy
policy" ,etc. Those pages don't get enough traffic to justify the

I'm intrigued by Pound as I've never heard of it. I have been looking
heavily at using Apache 2.2 for this same purpose but pound seems elegantly
simple in it's approach. The only drawback I can see is that the lack of
caching will cause dial-up users to stay connected to the backend servers
