Description
Since a few weeks we occasionally get the following exception:
Symfony\Component\HttpFoundation\Exception\ConflictingHeadersException
The request headers contain conflicting information regarding the origin of this request.The request has both a trusted Forwarded header and a trusted Client IP header, conflicting with each other with regards to the originating IP addresses of the request. This is the result of a misconfiguration. You should either configure your proxy only to send one of these headers, or configure Symfony to distrust one of them.
The issue only appears on Opera Mini on some generic smartphones, but Opera version 4 until 18 all cause this. If this is really something to be configured in Symfony, I think it should be done in our standard edition (Symfony config or AppCache), because I'm probably not the only one affected.
Anyone have a clue what to do?
