Hi,

I've tried to override the test client HTTP_HOST server param in my app config:

parameters:
    test.client.parameters:
        HTTP_HOST: symfony.com

However, in functional tests (WebTestCase), $client->getServerParameter('HTTP_HOST') does not return symfony.com but the default localhost.

The client is actually correctly configured at

but the call on the next line $client->setServerParameters($server); with an empty array erases HTTP_HOST because of the method definition:
