I will add only:-#10549 - makes server parameters to take precedence over URI.-#16265 - partially revererts#10549. Makes server parameters do not affect URI. But this is only true for `Client::request()`. It is still possible to set host for URI by `Client::setServerParameters()` when URI is realative (see examples below).I propose a compromise solution: add to HTTP_HOST header power to override URI when it is relative.Proposed solution:- if the request URI is relative, then use the HTTP_HOST header passed to Client::request() to generate an absolute URI- if the request URI is absolute, then ignore the HTTP_HOST header (as it now works)- do the same with HTTPS server parameterProfit:- fix BC Break- the documentation will be correct  -http://symfony.com/doc/2.8/routing/hostname_pattern.html#testing-your-controllers  -https://symfony.com/doc/2.8/testing.html#testing-configurationBefore:```$client->setServerParameters(['HTTP_HOST' => 'example.com']);$client->request('GET', '/');$this->assertEquals('http://example.com/', $client->getRequest()->getUri());$client->request('GET', '/', [], [], ['HTTP_HOST' => 'example.com']);$this->assertEquals('http://localhost/', $client->getRequest()->getUri());```Fixed (see last line):```$client->setServerParameters(['HTTP_HOST' => 'example.com']);$client->request('GET', '/');$this->assertEquals('http://example.com/', $client->getRequest()->getUri());$client->request('GET', '/', [], [], ['HTTP_HOST' => 'example.com']);$this->assertEquals('http://example.com/', $client->getRequest()->getUri());```Commits-------8c4a594 [BrowserKit] fixed BC Break for HTTP_HOST header; implemented same behaviour for HTTPS server parameter
