I know there's IPC, and also memcached. I've used IPC::Shareable before, but don't know if that's the route I'd wanna go.
It's not. IPC::Shareable is very slow. If you want to share data, use Cache::FileCache, Cache::Mmap, MLDBM::Sync, or IPC::MM.
Sorry to step in here, but could I use any of the caching modules you mentionned in mod_perl2?
Cache::Mmap (which I wrote) isn't threadsafe, but should work OK in a forking MPM. If anyone wants to contribute code to make it threadsafe (preferably without impacting single-threaded performance too much), I'll be very grateful. I'd do it myself, but I've never used threads, so I'm bound to get it wrong.
I haven't looked at the module's implementation, but if you have a C-level thread-safety issues, you may consider using libapr which provides a thread-safe mmap API.
