1. ".foo.com" - static means a non-dynamic value, something fixed.
2. You can have multiple, but have to call up the tree from your sub-class: $self->SUPER::cgiapp_init(). This is how inheritence works in Perl - if you override a base class method you have the option of calling it with SUPER::, or not. Often you need to put some thought into the right place to call it - before your sub-class does its thing or after. If they're both modifying the object's state this can be critical to getting it to do what you want.
