Before offering any advice, it might be a good idea for you to try and
explain your motivation for doing this a bit more. I suspect that there
are other, easier ways to do what you want.
For example, authorization can be handled in an autohandler with:
<%init>
if (user_has_access)
{
$m->call_next;
}
else
{
$m->comp('/components/login.mas'); # or an error document
}
</%init>
Where 'user_has_access' can involve calling some central function or
component.
Alternativly, you could put this in your root autohandler (so that you
have no duplicated code) with something like this:
<%init>
unless ($m->user->has_access( $m->base_comp->attr('require') )
{
$m->redirect('/', 301); # or whatever action you want to take
}
# ...
$m->call_next;
</%init>
Where each component would have an <%attr> block specifying the required
access:
<%attr>
require => 'admin'
</%attr>
