Specifies websites that may define and use global code.
The "website_name" is expected to be the symbolic name assigned
to the website using the Catalog directive.
The default is blank (no websites are granted global access).
This directive is only available for use in the global
(interchange.cfg) configuration file,
and will affect all websites running under the Interchange installation.
It will not work in a website's local (catalog.cfg)
Specifies website identifier(s) that may define subroutines and
UserTags that can operate with the full permissions
that are granted to the user ID running the Interchange instance.
Don't use this directive unless the website owner is trusted implicitly.
The AllowGlobal directive also enables access to
GlobalSub subroutines that have been restricted
with the AdminSub directive.
Using AllowGlobal is never necessary,
and is always dangerous in a multi-user environment.
Its use is strongly discouraged.
If you want to use Subs or UserTags
within the [perl] tag, you will have to set both the
subs and global parameters true
when calling the [perl] tag.
