Some questions/comments:
1) What happens when one or more disks fail during run time? The setting
name *proxy.config.http.cache.required* seems too confusing/restrictive that it
only applies to initialization.
2) Discussions on the IRC seem to indicate the
*proxy.config.http.cache.http* should not be used to indicate whether or not
cache is enabled. In particular, it is possible today to have
*proxy.config.http.cache.http* disabled globally, but, still have cache
initialized (allowing plugins to override *proxy.config.http.cache.http* for
individual transactions). So, using *proxy.config.http.cache.http = 0* to
ignore *proxy.config.http.cache.required* doesn't look correct and is not
compatible.
