Another thing I've done that can work well is to store something like
__TITLE__ in the page title, and then write a %filter section at the
end of autohandler which replaces that content with something from the
%stash (a global variable I set up that gets cleared at the start of
each request). It looks like this:
init.handler # I break this into a separate file so I can inherit
from it even from non-visual components, such as Ajax callbacks. You
can also just set all this stuff up in the .pl file that contains your
Handler.
<%init>
local(%stash) = (); # reset the stash at the start of every request
</%init>
autohandler
<%flags>
inherit => 'init.handler'
</%flags>
<head><title>__TITLE__</title></head>
<body>...
% $m->call_next;
</body>
<%filter>
my $title = 'My Site: ' . ($stash{title}||'');
s/__TITLE__/$title/;
</%filter>
page.html
<%init>
$stash{title} = 'This page title';
</%init>
blah blah
I realize this is kind of a hacky way around using methods + the like,
but it allows me to avoid having to use a %shared section in my
page.html if the contents of the title need to come from the database
(e.g. for an article page).
