=head1 PROXY SUPPORT
Many production servers operate using the common double-server approach,
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
+ $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.
+Additionally, you may be running your backend application on an insecure
+connection (port 80) while your frontend proxy is running under SSL. If there
+is a discrepancy in the ports, use the HTTP header C<X-Forwarded-Port> to
+tell Catalyst what port the frontend listens on. This will allow all URIs to
+be created properly.
+
+In the case of passing in:
+
+ X-Forwarded-Port: 443
+
+All calls to C<uri_for> will result in an https link, as is expected.
+
Obviously, your web server must support these headers for this to work.
In a more complex server farm environment where you may have your
configuration option to tell Catalyst to read the proxied data from the
headers.
- MyApp->config->{using_frontend_proxy} = 1;
-
+ 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;
+ MyApp->config(ignore_frontend_proxy => 1);
