110 | =head1 DESCRIPTION |
111 | |
fc7ec1d9 |
112 | The key concept of Catalyst is DRY (Don't Repeat Yourself). |
113 | |
114 | See L<Catalyst::Manual> for more documentation. |
115 | |
23f9d934 |
116 | Catalyst plugins can be loaded by naming them as arguments to the "use Catalyst" statement. |
1985c30b |
117 | Omit the C<Catalyst::Plugin::> prefix from the plugin name, |
23f9d934 |
118 | so C<Catalyst::Plugin::My::Module> becomes C<My::Module>. |
fc7ec1d9 |
119 | |
120 | use Catalyst 'My::Module'; |
121 | |
26e73131 |
122 | Special flags like -Debug and -Engine can also be specified as arguments when |
23f9d934 |
123 | Catalyst is loaded: |
fc7ec1d9 |
124 | |
125 | use Catalyst qw/-Debug My::Module/; |
126 | |
23f9d934 |
127 | The position of plugins and flags in the chain is important, because they are |
128 | loaded in exactly the order that they appear. |
fc7ec1d9 |
129 | |
23f9d934 |
130 | The following flags are supported: |
131 | |
132 | =over 4 |
133 | |
134 | =item -Debug |
135 | |
136 | enables debug output, i.e.: |
fc7ec1d9 |
137 | |
138 | use Catalyst '-Debug'; |
139 | |
23f9d934 |
140 | this is equivalent to: |
fc7ec1d9 |
141 | |
142 | use Catalyst; |
143 | sub debug { 1 } |
144 | |
fbcc39ad |
145 | =item -Dispatcher |
146 | |
147 | Force Catalyst to use a specific dispatcher. |
148 | |
23f9d934 |
149 | =item -Engine |
fc7ec1d9 |
150 | |
151 | Force Catalyst to use a specific engine. |
23f9d934 |
152 | Omit the C<Catalyst::Engine::> prefix of the engine name, i.e.: |
fc7ec1d9 |
153 | |
154 | use Catalyst '-Engine=CGI'; |
155 | |
fbcc39ad |
156 | =item -Home |
157 | |
158 | Force Catalyst to use a specific home directory. |
159 | |
160 | =item -Log |
161 | |
162 | Specify log level. |

1360 | =head1 CASE SENSITIVITY |
1361 | |
1362 | By default Catalyst is not case sensitive, so C<MyApp::C::FOO::Bar> becomes |
1363 | C</foo/bar>. |
1364 | |
1365 | But you can activate case sensitivity with a config parameter. |
1366 | |
1367 | MyApp->config->{case_sensitive} = 1; |
1368 | |

1369 | So C<MyApp::C::Foo::Bar> becomes C</Foo/Bar>. |
1370 | |
1371 | =head1 ON-DEMAND PARSER |
1372 | |
1373 | The request body is usually parsed at the beginning of a request, |
1374 | but if you want to handle input yourself or speed things up a bit |
1375 | you can enable on-demand parsing with a config parameter. |
1376 | |
1377 | MyApp->config->{parse_on_demand} = 1; |
1378 | |
1379 | =head1 PROXY SUPPORT |
1380 | |
1381 | Many production servers operate using the common double-server approach, with |
1382 | a lightweight frontend web server passing requests to a larger backend |
1383 | server. An application running on the backend server must deal with two |
1384 | problems: the remote user always appears to be '127.0.0.1' and the server's |
1385 | hostname will appear to be 'localhost' regardless of the virtual host the |
1386 | user connected through. |
1387 | |
1388 | Catalyst will automatically detect this situation when you are running both |
1389 | the frontend and backend servers on the same machine. The following changes |
1390 | are made to the request. |
1391 | |
1392 | $c->req->address is set to the user's real IP address, as read from the |
1393 | HTTP_X_FORWARDED_FOR header. |
1394 | |
1395 | The host value for $c->req->base and $c->req->uri is set to the real host, |
1396 | as read from the HTTP_X_FORWARDED_HOST header. |
1397 | |
1398 | Obviously, your web server must support these 2 headers for this to work. |
1399 | |
1400 | In a more complex server farm environment where you may have your frontend |
1401 | proxy server(s) on different machines, you will need to set a configuration |
1402 | option to tell Catalyst to read the proxied data from the headers. |
1403 | |
1404 | MyApp->config->{using_frontend_proxy} = 1; |
1405 | |
1406 | If you do not wish to use the proxy support at all, you may set: |
d1a31ac6 |
1407 | |
fbcc39ad |
1408 | MyApp->config->{ignore_frontend_proxy} = 1; |
1409 | |
1410 | =head1 THREAD SAFETY |
1411 | |
1412 | Catalyst has been tested under Apache 2's threading mpm_worker, mpm_winnt, |
1413 | and the standalone forking HTTP server on Windows. We believe the Catalyst |
1414 | core to be thread-safe. |
1415 | |
1416 | If you plan to operate in a threaded environment, remember that all other |
1417 | modules you are using must also be thread-safe. Some modules, most notably |
1418 | DBD::SQLite, are not thread-safe. |
