You don't need to use $ENV. If you're using handlers you could use 

You could certainly create a big hash at startup and grab stuff out of 
it that way, where the top level key is the hostname. If the data that 
you want to store is just strings though, this might be overkill. If, 
however, you want to create deeper datastructures from a somewhere, then 
this would be a perfectly acceptable way to do that. PerlSetVar is great 
with just strings, but not for anything any more complicated than that. 
It does have to be static configuration.

All the other limitations that André mentioned are completely accurate
