Trusting Proxies
5+
================
6+
7+
If you find yourself behind some sort of proxy - like a load balancer - then
8+
certain header information may be sent to you using special ``X-Forwarded-*``
9+
headers. For example, the ``Host`` HTTP header is usually used to return
10+
the requested host. But when you're behind a proxy, the true host may be
11+
stored in a ``X-Forwarded-Host`` header.
12+
13+
Since HTTP headers can be spoofed, Symfony2 does *not* trust these proxy
14+
headers by default. If you are behind a proxy, you should manually whitelist
15+
your proxy::
16+
17+
use Symfony\Component\HttpFoundation\Request;
18+
19+
$request = Request::createFromGlobals();
20+
// only trust proxy headers coming from this IP address
21+
$request->setTrustedProxies(array(192.0.0.1));
22+
23+
Configuring Header Names
24+
------------------------
25+
26+
By default, the following proxy headers are trusted:
27+
28+
* ``X-Forwarded-For`` Used in :method:`Symfony\\Component\\HttpFoundation\\Request::getClientIp`;
29+
* ``X-Forwarded-Host`` Used in :method:`Symfony\\Component\\HttpFoundation\\Request::getHost`;
30+
* ``X-Forwarded-Port`` Used in :method:`Symfony\\Component\\HttpFoundation\\Request::getPort`;
31+
* ``X-Forwarded-Proto`` Used in :method:`Symfony\\Component\\HttpFoundation\\Request::getScheme` and :method:`Symfony\\Component\\HttpFoundation\\Request::isSecure`;
32+
33+
If your reverse proxy uses a different header name for any of these, you
34+
can configure that header name via :method:`Symfony\\Component\\HttpFoundation\\Request::setTrustedHeaderName`::
35+
36+
$request->setTrustedHeaderName(Request::HEADER_CLIENT_IP, 'X-Proxy-For');
37+
$request->setTrustedHeaderName(Request::HEADER_CLIENT_HOST, 'X-Proxy-Host');
38+
$request->setTrustedHeaderName(Request::HEADER_CLIENT_PORT, 'X-Proxy-Port');
39+
$request->setTrustedHeaderName(Request::HEADER_CLIENT_PROTO, 'X-Proxy-Proto');
40+
41+
Not trusting certain Headers
42+
----------------------------
43+
44+
By default, if you whitelist your proxy's IP address, then all four headers
45+
listed above are trusted. If you need to trust some of these headers but
46+
not others, you can do that as well::
47+
48+
// disables trusting the ``X-Forwarded-Proto`` header, the default header is used
49+
$request->setTrustedHeaderName(Request::HEADER_CLIENT_PROTO, '');

* If you answer yes to "New feature?", you must submit a pull request to the
315+
documentation and reference it under the "Doc PR" section;

* If you answer yes to "BC breaks?", the patch must contain updates to the
318+
relevant CHANGELOG and UPGRADE files;

* If you answer no to "Tests pass", you must add an item to a todo-list with
324+
the actions that must be done to fix the tests;
325+
326+
* If the "license" is not MIT, just don't submit the pull request as it won't
327+
be accepted anyway.

330+
relevant items:

334+
- [ ] fix the tests as they have not been updated yet
335+
- [ ] submit changes to the documentation
336+
- [ ] document the BC breaks
337+
338+
If the code is not finished yet because you don't have time to finish it or
