Yes, possible. Just assign the data to a named global at startup time. ie. <httpd.conf> PelrModule My::Module </httpd.conf> <My/Module.pm> package My::Module; use Mymodule; our $data = Mymodule->new; </My/Module.pm> Than anywhere you want, just refer to $My::Module::data Generally, when doing something like that, you want to make 100% certain that your data is read-only, otherwise, any changes to it won't be reflected for every child process, and tons of memory will get suddently unshared. To avoid that, checkout the various ways you can make something truly read-only.
