=head1 NAME
Mason::Manual::RequestDispatch - How request paths get mapped to page
components
=head1 DESCRIPTION
Given the request path
/news/sports/hockey
Mason searches for the following components in order, setting $m->path_info as
noted.
/news/sports/hockey.{mp,mc}
/news/sports/hockey/index.{mp,mc}
/news/sports/hockey/dhandler.{mp,mc}
/news/sports/dhandler.{mp,mc} # $m->path_info = hockey
/news/sports.{mp,mc} # $m->path_info = hockey (but see next section)
/news/dhandler.{mp,mc} # $m->path_info = sports/hockey
/news.{mp,mc} # $m->path_info = sports/hockey (but see next section)
/dhandler.{mp,mc} # $m->path_info = news/sports/hockey
where C<< .{mp,mc} >> means either C<.mp> (indicating a I<pure-perl>
component). or C<.mc> (indicating a I<top-level> component).
The following sections describe these elements in more detail.
=head2 Autoextended path
The request path is suffixed with ".mp" and ".mc" to translate it to a
component path.
/news/sports/hockey.{mp,mc}
=head2 Index
An index matches its exact directory, nothing underneath.
/news/sports/hockey/index.{mp,mc}
=head2 Dhandlers
A dhandler matches its directory as well as anything underneath, setting C<<
$m->path_info >> to the remainder.
/news/sports/hockey/dhandler.{mp,mc}
/news/sports/dhandler.{mp,mc} # $m->path_info = hockey
/news/dhandler.{mp,mc} # $m->path_info = sports/hockey
/dhandler.{mp,mc} # $m->path_info = news/sports/hockey
=head2 Partial paths
A component can match an initial part of the URL, setting C<< $m->path_info >>
to the remainder:
/news/sports.{mp,mc} # $m->path_info = hockey
/news.{mp,mc} # $m->path_info = sports/hockey
Since this isn't always desirable behavior, it must be explicitly enabled for
the component. Mason will call method C<allow_path_info> on the component
class, and will only allow the match if it returns true:
<%class>
method allow_path_info { 1 }
</%class>
The default C<allow_path_info> returns false.
C<allow_path_info> is not checked on dhandlers, since the whole point of
dhandlers is to match partial paths.
=head2 Routes
It is possible to use route syntax to more elegantly parse C<< $m->path_info >>
for dhandlers and partial paths, e.g.
<%class>
route "{year:[0-9]+}/{month:[0-9]{2}}";
</%class>
