+B<This method is deprecated> as of version 2.11. If you have overridden it,
+please override C<is_model_applicable> instead, and change the return type
+from Maypole:Constants to true/false.
+
+=head3 is_model_applicable
+
+Returns true or false to indicate whether the request is valid.
+
+The default implementation checks that C<< $r->table >> is publicly
+accessible and that the model class is configured to handle the
+C<< $r->action >>.
+
+=head3 authenticate
+
+Returns a Maypole::Constant to indicate whether the user is
+authenticated for
+the Maypole request.
+
+The default implementation returns C<OK>
+
+=head3 model_class
+
+Returns the perl package name that will serve as the model for the
+request. It corresponds to the request C<table> attribute.
+
+=head3 additional_data
+
+Called before the model processes the request, this method gives you a
+chance
+to do some processing for each request, for example, manipulating
+C<template_args>.
+
+=head3 objects
+
+Get/set a list of model objects. The objects will be accessible in the
+view
+templates.
+
+If the first item in C<$self-E<gt>args> can be C<retrieve()>d by the model
+class,
+it will be removed from C<args> and the retrieved object will be added
+to the
+C<objects> list. See L<Maypole::Model> for more information.
+
+=head3 template_args
+
+ $self->template_args->{foo} = 'bar';
+
+Get/set a hash of template variables.
+
+=head3 stash
+
+A place to put custom application data. Not used by Maypole itself.
+
+=head3 template
+
+Get/set the template to be used by the view. By default, it returns
+C<$self-E<gt>action>
+
+=head3 exception
+
+This method is called if any exceptions are raised during the
+authentication
+or
+model/view processing. It should accept the exception as a parameter and
+return
+a Maypole::Constant to indicate whether the request should continue to
+be
+processed.
+
+=head3 error
+
+Get/set a request error
+
+=head3 output
+
+Get/set the response output. This is usually populated by the view
+class. You
+can skip view processing by setting the C<output>.
+
+=head3 document_encoding
+
+Get/set the output encoding. Default: utf-8.
+
+=head3 content_type
+
+Get/set the output content type. Default: text/html
+
+=head3 send_output
+
+Sends the output and additional headers to the user.
+
+=head3 call_authenticate
+
+This method first checks if the relevant model class
+can authenticate the user, or falls back to the default
+authenticate method of your Maypole application.
+
+
+=head3 call_exception
+
+This model is called to catch exceptions, first after authenticate, then after
+processing the model class, and finally to check for exceptions from the view
+class.
+
+This method first checks if the relevant model class
+can handle exceptions the user, or falls back to the default
+exception method of your Maypole application.
+
+=head3 make_random_id
+
+returns a unique id for this request can be used to prevent or detect repeat
+submissions.
+
+=head3 get_protocol
+
+Returns the protocol the request was made with, i.e. https
+
+=head3 redirect_request
+
+Sets output headers to redirect based on the arguments provided
+
+Accepts either a single argument of the full url to redirect to, or a hash of named parameters :
+
+$r->redirect_request('http://www.example.com/path');
+
+or
+
+$r->redirect_request(protocol=>'https', domain=>'www.example.com', path=>'/path/file?arguments', status=>'302', url=>'..');
+
+The named parameters are protocol, domain, path, status and url
+
+Only 1 named parameter is required but other than url, they can be combined as required and current values (from the request) will be used in place of any missing arguments. The url argument must be a full url including protocol and can only be combined with status.
+
+=head3 redirect_internal_request
+
+=head3 handler
+
+This method sets up the class if it's not done yet, sets some
+defaults and leaves the dirty work to handler_guts.
+
+=head3 handler_guts
+
+This is the main request handling method and calls various methods to handle the request/response
+and defines the workflow within Maypole.
+
+Currently undocumented and liable to be refactored without warning.
