-Special flags like C<-Debug> and C<-Engine> can also be specified as
+Special flags like C<-Debug> can also be specified as
arguments when Catalyst is loaded:
use Catalyst qw/-Debug My::Module/;
This sets the log level to 'debug' and enables full debug output on the
error screen. If you only want the latter, see L<< $c->debug >>.
-=head2 -Engine
-
-Forces Catalyst to use a specific engine. Omit the
-C<Catalyst::Engine::> prefix of the engine name, i.e.:
-
- use Catalyst qw/-Engine=CGI/;
-
=head2 -Home
Forces Catalyst to use a specific home directory, e.g.:
MYAPP_WEB_HOME. If both variables are set, the MYAPP_HOME one will be used.
If none of these are set, Catalyst will attempt to automatically detect the
-home directory. If you are working in a development envirnoment, Catalyst
+home directory. If you are working in a development environment, Catalyst
will try and find the directory containing either Makefile.PL, Build.PL or
dist.ini. If the application has been installed into the system (i.e.
you have done C<make install>), then Catalyst will use the path to your
-application module, without the .pm extension (ie, /foo/MyApp if your
+application module, without the .pm extension (e.g., /foo/MyApp if your
application was installed at /foo/MyApp.pm)
=head2 -Log
Note that L<< forward|/"$c->forward( $action [, \@arguments ] )" >> implies
an C<< eval { } >> around the call (actually
-L<< execute|/"$c->execute( $class, $coderef )" >> does), thus de-fatalizing
-all 'dies' within the called action. If you want C<die> to propagate you
-need to do something like:
+L<< execute|/"$c->execute( $class, $coderef )" >> does), thus rendering all
+exceptions thrown by the called action non-fatal and pushing them onto
+$c->error instead. If you want C<die> to propagate you need to do something
+like:
$c->forward('foo');
die join "\n", @{ $c->error } if @{ $c->error };
when they are invoked within the visited action. This is different from the
behavior of L<< forward|/"$c->forward( $action [, \@arguments ] )" >>, which
continues to use the $c->action object from the caller action even when
-invoked from the callee.
+invoked from the called action.
C<< $c->stash >> is kept unchanged.

+C<use_request_uri_for_path> - Controls if the C<REQUEST_URI> or C<PATH_INFO> environment
+variable should be used for determining the request path.
+
+Most web server environments pass the requested path to the application using environment variables,
+from which Catalyst has to reconstruct the request base (i.e. the top level path to / in the application,
+exposed as C<< $c->request->base >>) and the request path below that base.
+
+There are two methods of doing this, both of which have advantages and disadvantages. Which method is used
+is determined by the C<< $c->config(use_request_uri_for_path) >> setting (which can either be true or false).
+
+=over
+
+=item use_request_uri_for_path => 0
+
+This is the default (and the) traditional method that Catalyst has used for determining the path information.
+The path is generated from a combination of the C<PATH_INFO> and C<SCRIPT_NAME> environment variables.
+The allows the application to behave correctly when C<mod_rewrite> is being used to redirect requests
+into the application, as these variables are adjusted by mod_rewrite to take account for the redirect.
+
+However this method has the major disadvantage that it is impossible to correctly decode some elements
+of the path, as RFC 3875 says: "C<< Unlike a URI path, the PATH_INFO is not URL-encoded, and cannot
+contain path-segment parameters. >>" This means PATH_INFO is B<always> decoded, and therefore Catalyst
+can't distinguish / vs %2F in paths (in addition to other encoded values).
+
+=item use_request_uri_for_path => 1
+
+This method uses the C<REQUEST_URI> and C<SCRIPT_NAME> environment variables. As C<REQUEST_URI> is never
+decoded, this means that applications using this mode can correctly handle URIs including the %2F character
+(i.e. with C<AllowEncodedSlashes> set to C<On> in Apache).
+
+Given that this method of path resolution is provably more correct, it is recommended that you use
+this unless you have a specific need to deploy your application in a non-standard environment, and you are
+aware of the implications of not being able to handle encoded URI paths correctly.
+
+However it also means that in a number of cases when the app isn't installed directly at a path, but instead
+is having paths rewritten into it (e.g. as a .cgi/fcgi in a public_html directory, with mod_rewrite in a
+.htaccess file, or when SSI is used to rewrite pages into the app, or when sub-paths of the app are exposed
+at other URIs than that which the app is 'normally' based at with C<mod_rewrite>), the resolution of
+C<< $c->request->base >> will be incorrect.

If you do not wish to use the proxy support at all, you may set:
- MyApp->config(ignore_frontend_proxy => 1);
+ MyApp->config(ignore_frontend_proxy => 0);

+=head2 Note about psgi files
+
+Note that if you supply your own .psgi file, calling
+C<< MyApp->psgi_app(@_); >>, then B<this will not happen automatically>.
+
+You either need to apply L<Plack::Middleware::ReverseProxy> yourself
+in your psgi, for example:
+
+ builder {
+ enable "Plack::Middleware::ReverseProxy";
+ MyApp->psgi_app
+ };
+
+This will unconditionally add the ReverseProxy support, or you need to call
+C<< $app = MyApp->apply_default_middlewares($app) >> (to conditionally
+apply the support depending upon your config).
+
+See L<Catalyst::PSGI> for more information.
