global vs multi-process

["David Willams" <suppressed>]

Hello modperl, 

I'm coming to grips with multi-process vs. multi-threaded limitations (and benefits!).

For example, during start up, for sharing read-only data among child processes, we do something like:

%CACHE = get_data( );

Child processes cannot update
%CACHE, so what other apache methods or architectural strategies exist
(creative, elaborate, etc) or have been used to update a similar hash?
Is this not a common requirement?

Can a separate apache daemon-like module be used to manage that hash?

Unfortunately, a database will not work for my current problem.

Thanks,
-D
