Dear Rodrigo,
Some of the man pages are unfortunately quite old and show many
potential for improvements.
Please check the updated documentation at
https://bitbucket.org/naviserver/naviserver/commits/8c036c9c5b830d24c469eb1eb4a6c395fdf73226
in short: the blueprint contains just namespaced variables (global
variables, which are not
in the topmost namespace "::"). If your application needs global
variables in the interpreter,
define your own Tcl namespace and keep your variables there.
all the best

In naviserver-4.99.15/doc/html/manual/files/tcl-overview.html we read:
Tcl Interpreters
During NaviServer initialization, only one interpreter exists. While
modules are loaded and initialized, they may add procedures to the
interpreter. When initialization is complete (all modules are loaded
and all Tcl libraries have been executed), the interpreter may no
longer be changed.
Each connection thread that requires Tcl will create a copy of the
original interpreter.
<<<
That they may add procedures does not exclude that they also may
add global variables.
After some experiments, it seems to me that at some point global
variables in the loaded modules *and* libraries are unset, I suppose
immeadately after modules are loaded and libraries are executed.
Is it true? When it happens? An explicit hint to it in the documentation
would help beginners a lot.
It is a question of taste: I would preffer to decide what variables
to unset and not let the server do it automatically, but it could
be a source of chaos.
Thanks
Rodrigo.
