+=head1 ON-DEMAND PARSER

+    
+=head1 PROXY SUPPORT
+
+Many production servers operate using the common double-server approach, with
+a lightweight frontend web server passing requests to a larger backend
+server.  An application running on the backend server must deal with two
+problems: the remote user always appears to be '127.0.0.1' and the server's
+hostname will appear to be 'localhost' regardless of the virtual host the
+user connected through.
+
+Catalyst will automatically detect this situation when you are running both
+the frontend and backend servers on the same machine.  The following changes
+are made to the request.
+
+    $c->req->address is set to the user's real IP address, as read from the
+    HTTP_X_FORWARDED_FOR header.
+    
+    The host value for $c->req->base and $c->req->uri is set to the real host,
+    as read from the HTTP_X_FORWARDED_HOST header.
+
+Obviously, your web server must support these 2 headers for this to work.
+
+In a more complex server farm environment where you may have your frontend
+proxy server(s) on different machines, you will need to set a configuration
+option to tell Catalyst to read the proxied data from the headers.
+
+    MyApp->config->{using_frontend_proxy} = 1;
+    
+If you do not wish to use the proxy support at all, you may set:
+
+    MyApp->config->{ignore_frontend_proxy} = 1;
+
+=head1 THREAD SAFETY
+
+Catalyst has been tested under Apache 2's threading mpm_worker, mpm_winnt,
+and the standalone forking HTTP server on Windows.  We believe the Catalyst
+core to be thread-safe.
+
+If you plan to operate in a threaded environment, remember that all other
+modules you are using must also be thread-safe.  Some modules, most notably
+DBD::SQLite, are not thread-safe.
