Deny websites the ability to request access to absolute filenames on the system.
This is a Yes or No directive.
The default is No.
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)
This directive controls whether tags such as [file] and
[include] etc. can request access to any file on the system
If this directive is set true (Yes) then only files relative
to the website's home directory may be requested.
The website's home directory is defined by the Catalog
global configuration directive.
If this directive is set false (No) then any file may be
requested (subject to user permissions).
This does not apply when testing to see whether a file exists,
as with [if file].
This operation is allowed regardless of the NoAbsolute value.
The default (No) should be changed to Yes in a multi-user
environment to minimise security risks.
