I'm pleased to hear that you have plans to re-integrate gcache, or rather
something similar, back into mod_ssl.

What about maintaining a persistent connection to a gcache server on a
per-child or per-thread basis within Apache?
And possibly having a list of gcache servers to connect to for
fail-over?
And possibly connecting to a "load-balancer" which then tells mod_ssl which
gcache server to connect to?
We have a real need for such a beast and would love to help out.
About NPS, does this library "work" on multi-processor machines? That is,
are NPS threads bound to a single CPU?
