Sharing variables (I believe you really want to do so between 
requests) can be done using normal Perl things like global 
variables (or, if you want many workers to share the same data, 
using shared memory, see various perl modules available on CPAN).

Calling the handler at access phase isn't something you can do 
without modifications of the code.  On the other hand, it may be a 
good idea to use auth request module[1] instead, and write a 
subrequest handler in embedded perl.
