Imagine a ``User`` entity which can be a normal user or a premium user. When

Routing and X-FORWARDED Headers
180+
-------------------------------
181+
182+
To ensure that the Symfony Router generates urls correctly with Varnish,
183+
proper ```X-Forwarded``` headers must be added so that Symfony is aware of
184+
the original port number of the request. Exactly how this is done depends
185+
on your setup. As a simple example, Varnish and your web server are on the
186+
same machine and that Varnish is listening on one port (e.g. 80) and Apache
187+
on another (e.g. 8080). In this situation, Varnish should add the ``X-Forwarded-Port``
188+
header so that the Symfony application knows that the original port number
189+
is 80 and not 8080.
190+
191+
If this header weren't set properly, Symfony may append ``8080`` when generating
192+
absolute URLs:
193+
194+
.. code-block:: text
195+
196+
sub vcl_recv {
197+
if (req.http.X-Forwarded-Proto == "https" ) {
198+
set req.http.X-Forwarded-Port = "443";
199+
} else {
200+
set req.http.X-Forwarded-Port = "80"
201+
}
202+
}
203+
204+
.. note::
205+
206+
Remember to configure :ref:`framework.trusted_proxies<reference-framework-trusted-proxies>`
207+
in the Symfony configuration so that Varnish is seen as a trusted proxy
208+
and the ``X-Forwarded-`` headers are used.
